Answer:

(1, -3)

(2, -5)

(3, -7)

Step-by-step explanation:

Randomly choose three values for "x". Substitute each of them separately into the formula to find the "y". Then write the solution as an ordered pair (x, y).

I will choose x=1, x=2 and x=3.

When x=1:

y = -2x - 1

y = -2(1) - 1

y = -2 - 1

y = -3

(1, -3)

When x=2:

y = -2x - 1

y = -2(2) - 1

y = -4 - 1

y = -5

(2 , -5)

When x=3:

y = -2x - 1

y = -2(3) - 1

y = -6 - 1

y = -7

(3, -7)

(1,-3), (2,-5), and (3,-7)

An easy way to find this is set you a definite y value. So try -3 as the value for y. Solve for x as normal so -3=-2x-1. Add 1 on both sides to get -2=-2x. Divide on both sides by -2 and get 1=x. Since the slope is -2 you keep subtracting -2 from -3 and you’ll get -5 when x=2 and so on.
