On these questions for 5 stars and 1. suppose the equation of the axis of symmetry for a quadratic function is x = -3 and one of the x-intercepts is -8. what is the other x-intercept? 2. if the equation of the axis of symmetry of a quadratic function is x = 0, and one of the x-intercept is -4, what is the other x-intercept?

Two
===
x=0 is the y axis. So the other x intercept is a mirror image of x = - 4.
x = 4 is the other x value for the intercept.
(4,0) is the other intercept. << answer.

One
===
Axis of symmetry is x = - 3
One of the intercepts is (- 8,0) That is 5 units to the left of (-3,0) so now yo much go 5 units to the right of (-3,0)
That will take you to -3 + 5 = 2
(2,0) is the other intercept <<<<< answer.

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
