Question

write an equation in slope intercept form for the line that contains the given points, (-8,6) and (-6,9) write an equation in slope intercept form for the line that contains the given points, (-8,6) and (-6,9) @Mathematics

Answer 1

First you have to find the slope. m = (y1-y2)/(x1-x2)
m=(9-6)/(-6 - (-8))
m= 3/2

Now you take the equation y = 3/2 x +b, pick one of the points, plug in the x and y values, and solve for b.

Answer 2

For example if we use (-8,6) we get
6 = (3/2) (-8) + b
6 = - 12 +b (add 12 to both sides)
b = 18

so y = 3/2 x + 18
