Olin [163]

Answer:

y=-4x+2

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

Step 1

Find the slope m

Let

A(1,-2),B(2.-6)

m=(-6+2)/(2-1)=-4

Step 2

Find the value of b

we have

m=-4

A(1,-2)

substitute in the equation of the line

y=mx+b

-2=(-4)(1)+b

-2=-4+b

b=2

The equation in slope intercept form is equal to

y=-4x+2
