Answer:

y=-8x+10

Step-by-step explanation:

Slope intercept form is y=mx+b

We know that the slope, m, equals -8, so we can plug this in.

y=-8x+b

All we need now is b, which is the y-intercept. We can find b by plugging in the point and solving it as an equation.

2=-8(1)+b

2=-8+b

10=b

After we have found b, we just plug it into the equation.

y=-8x+10
