Question

(-10, -6); m=-5/8

Answer 1

I suppose you want to find the equation of a line with slope -5/8 and a point (-10,-6)

use the point slope formula

y - y1 = m(x - x1)

you plug your y in for y1 and your x in for x1

so

y - (-6) = -5/8(x - (-10))

y + 6 = -5/8(x + 10)

y + 6 = -5/8x - 6.25

Now add 6 to both sides and get

y = -5.8 - .25
