Write an equation in slope-intercept form of the line that passes through the given ,3) & (-3,1)

Y = X+4

Step-by-step explanation:

They are asking for the equation Y = mX + b

Therefore we need to find the slope and the interception of the given points.

The slope of the line AB

mAB= (yB -yA) / (xB -xA)

The data given is: A (-1, 3) and B (-3, 1)

Then the slope is: mAB= (1 -3) / (-3 -(-1)) = 1

From the equation Y = mX + b, clear b

b = Y - mX

Now substitute any given point to find the interception (b) in the equation

b = Y - mX

Lets choose point A (-1, 3), remember mAB= 1

b = 3 - ( 1(-1)) = 4

b = 4

Therefore the general equation is:

Y = mX + b --> Y = 1X + 4 --> Y = X+4
