What is an equation of the line that passes through the points (-5, -8) and (5,4)?

Question

i need to find b

Answer 1

Let's first find the slope of the line passing between these two points.

m = (y2- y1)/(x2-x1)

m=(4--8)/(5--5)

m=(4+8)/(5+5)

m=12/10 = 6/5

Now that we have a point and a slope, we can use point-slope form to get an equation of the line.

Here is the formula for point slope form:

y-y1=m(x-x1)

I am going to use the point (5,4) as the point as x1=5 and y1=4.

Thus,

y-4 = 6/5(x-5) >>

y-4 = 6/5x -6

y=6/5x -2
