Question

The relationship between x and y is y = (x - 2)2.

How does the value of y change as the value of x increases from -4 to -2?

Answer 1

In slope-intercept form, this equation is:\[y = 2x - 4\]

You can plug in the two values for x to get their respective y values:\[y = 2(-4)-4 = -12\]\[y = 2(-2)-4 = 0\]The y value went from -12 to 0, so it increased by 12 as x increased from -4 to -2
