Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
(-8,7), m = 4

Respuesta :

Step-by-step explanation:

y-y1=m(x-x1)

y-7=4(x+8)

y-7=4x+32

4x-y=-39

Answer:

y = 4x + 39

Step-by-step explanation:

  • The line passes through point (-8,7) and;
  • Has a slope (m) = 4

Let's take another point (x,y) on the line.

Slope (m) = change in y ÷ change in x

∴ m = [tex]\frac{y - 7}{x - -8} = 4[/tex]

y = 4x + 32 + 7

y = 4x + 39
