Question

which equation represents the line that passes through the point (1,5) and has a slope of -2?

Answer 1

The coordinate point is (x,y).
A linear equation is y=mx+b where m=slope.
You would plug in the values for x and y in the formula.
\[y=mx+b\]\[5=-2(1)+b\]Then solve for b.
After that, you should have the equation that you're looking for.

Answer 2

1. y=-2x+7
2. y=-2x+11
3. y= 2x-9
4. y= 2x+3

Which one is it?

Answer 3

After you solve for b, you should get b=7.

You plug that into y=mx+b. So it will be y=-2x+7

Answer 4

thanks! its correct!
