Question

Complete the equation for the linear function whose graph contains the point (7, 8) and has a slope of −1.2.
y = x +

Answer 1

@iGreen

Answer 2

Okay, for this one we plug it into point-slope form and simplify it.

\(y - y_1 = m(x - x_1)\)

Can you plug in the slope and the point into here?

Answer 3

y-8=-1.2(x-7) @iGreen

Answer 4

Yes, now we distribute -1.2 into the parenthesis:

y - 8 = -1.2(x - 7)

y - 8 = -1.2x + 8.4

Add 8 to both sides, what's 8.4 + 8?

Answer 5

16.4

Answer 6

Yes, so we have:

y = -1.2x + 16.4

Answer 7

That's your final answer.
