A line has equation y=3x+4, state the gradient and the y-intercept. The gradient is always the number in front of the x, in this case it will be 3. Whereas for the y-intercept, it will always be the value that y equates to when x=0, in this case the y-intercept is (0,4).

The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.

To find the x-intercepts of a quadratic equation, let y = 0. Write down the new equation ax squared + bx + c = 0 and the quadratic formula that gives the solution as x = -b plus or minus the square root of (b squared - 4ac), all divided by 2a. The quadratic formula can give zero, one or two solutions.
