What is the slop and y intercept for 10x + 5y=100

slope=-2       y-intercept=20

Step-by-step explanation:

10x+5y=100

5y=-10x+100

y=-2x+20

y=mx+b (m is slope and b is the y-intercept)

slope= -2

y intercept= (0,20) hope this helps

Step-by-step explanation:

1 1/5

step-by-step explanation:

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
