Answer: y=-2x+0
Let’s rewrite the equation
y=-2x-13
Knowing that the new equation is parallel to this will only tell us the slope. When an equation is parallel to another, it has the same slope but different y-intercept. So, our equation will have the same slope.
This is our current equation: y=-2x+b
Now we need to solve to b. We’ll do this by substituting the point into the equation and solving.
y=-2x+b
*substitute point*
-8=-2(4)+b
-8=-8+b
+add 8 on both sides*
0=b
Let’s add this into our equation— y=-2x+0 is our final answer
