Answer:

Both answers are correct

Step-by-step explanation:

both y = 1 - 3/2x and y = 1 + -3/2x are correct answers, it is just that y= 1 - 3/2x is the simpler version. Adding a negative number is the same as subtracting a positive.

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

$y=-4x+2$
