Answer:
y=-2x+8
Step-by-step explanation:
We are trying to put this equation into slope intercept form, so we need to put the information given into y=mx + b (m is slope, b is the y intercept). So we know that the slope is -2, so y=-2x+b. Next, we need to find the y intercept. So substitute the ordered pair into the equation so, 12=-2(-2)+b. Simplify: 12=4+b. Solve: b=8. Hope it helps
