Question

Find the equation of the line (y=mx+b) with a slope -4 and passes through (3,-2)

Answer 1

Solution

For this case we have the slope given:

m= -4

And we have a point (x= 3, y=-2)

So we can use the formula:

y= mx+b

And replacing we got

-2 = -4(3) +b

b= -2 +12= 10

Then we have:

y= -4x +10
