Helppp Find the slope of the line that contains the points
(-3,-4) and (5,5)

9/8

Step-by-step explanation:

We can use the slope formula

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

   = (5 - -4)/(5 - -3)

   = (5+4)/(5+3)

  9/8

Step-by-step explanation:

(5 + 4)/(5 + 3) = 9/8 is the slope

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
