how to find x intercept using slope?

To solve this, first find the equation of our line. The form of the question gives it to us very directly. We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis.

If the equation is in standard form:ax+by=c then you just set x equal to 0 to find the y intercept and set y equal to 0 to find the x intercept. It makes sense, right. The y intercept is when the line crosses the y axis, so x will always be 0, so that is why we set x equal to 0.

To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form). In this case, we end up with the square root of a negative number, so there are no x-intercepts.

The x-intercepts are points where the graph of a function or an equation crosses or “touches” the x-axis of the Cartesian Plane. You may think of this as a point with y-value of zero. To find the x-intercepts of an equation, let y = 0 y = 0 y=0 then solve for x. In a point notation, it is written as (x,0).

To find the slope, we will need two points from the line. Pick two x's and solve for each corresponding y: If, say, x = 3, then y = ( 2/3 )(3) - 4 = 2 - 4 = -2. If, say, x = 9, then y = ( 2/3 )(9) - 4 = 6 - 4 = 2.

To find the y-intercept let x = 0 and solve for y. Step 3: Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form).

The form of the equation is Ax + By = C, so subtract Ax from both sides and divide both sides by B. You get : y = -(A/B)x +C/B. This is the slope intercept form.

To find the x intercepts, set y = 0 in the above equation and solve for x. To find the y intercepts, set x = 0 and solve for y.

Summary. The slope-intercept form of a line is: y=mx+b where m is the slope and b is the y-intercept. The y-intercept is always where the line intersects the y-axis, and will always appear as (0,b) in coordinate form.

This can be done by calculating the slope between two known points of the line using the slope formula. Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

To find the y-intercept(s) (the point where the graph crosses the y-axis), substitute in 0 for x and solve for y or f(x). To find the x-intercept(s) (the point where the graph crosses the x-axis â€“ also known as zeros), substitute in 0 for y and solve for x.

The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Rewrite in slope-intercept form. Subtract 3x 3 x from both sides of the equation. Divide each term by 4 4 and simplify.

But we can utilize the given slope and a point to find it. Substitute the known values into the slope-intercept formula, and then solve for the unknown value of b. Back substitute the value of the slope and the solved value of the y-intercept into y = m x + b y = mx + b y=mx+b.

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y.
