Question

slope=-2,through (-7,5)

Answer 1

Guessing you want this in y = mx+b form?

Answer 2

Okay so lets replace (x,y) in the equation
y-y1=m(x-x1)

Answer 3

i got this everyone

Answer 4

:)

Answer 5

so lets replace y and x and m now that they have given you the slope
y-5=-2(x+7)

Answer 6

solve it:
y-5=-2x-14
y=-2x-9
there you go ;)

Answer 7

now graph it
