Answer 1

Answer:

Step-by-step explanation:

Question one

The slope is simply read. It is - 2

So far what you have is

y = mx + b

m = -2

y = - 2x + b

The point is a little different

(-1,1) means

x = - 1

y = 1

y = -2x + b

1 = -2(1) + b

1 = - 2 + b

1 + 2 = - 2 + 2 + b

3 = b

Complete line

y = -2x + 3

Problem 2

(0,-6 is where you should start. That's the y intercept. In the equation y = mx + b it gives you b immediately.

y = mx + b

-6 = 0m + b

b = - 6

The x intercept occurs when y  = 0

0 = m(-2) - 6                      Add 6 to both sides

6 = - 2m - 6 + 6                

6 = -2m                             Divide by -2

6/-2 = m

m = - 3

Equation

y = -3x - 6
