Question

Find the equation of the linear function represented by the table below in slope-

intercept form.

Answer 1

9514 1404 393

Answer:

y = -4x -2

Explanation:

The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (-10 -10)/(2 -(-3)) = -20/5 = -4

__

The y-intercept is given by ...

b = y1 -m(x1)

b = 10 -(-4)(-3) = 10 -12 = -2

Then the slope-intercept equation is ...

y = mx +b

y = -4x -2
