The point-slope form of the equation of the line with a slope of - 2 and an x-intercept of - 1

Step-by-step explanation:

y - y1 = m(x - x1)

slope(m) = -2

x int of -1 is the same as (-1,0)x1 = -1 and y1 = 0

now we sub

y - 0 = -2(x - (-1) =

y - 0 = -2(x + 1) <

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

answer: the answer is simply nothing.

step-by-step explanation: because there is no ending to this question
