Lines c and d are parallel. the equation of line c is y= -3x - 5. what is the
equation of line d?

Step-by-step explanation:

Parallel lines have the same slope.

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

We have the equation of a line c:

Therefore the equation of a line d parallel to a line c is:

The lines c and d are different. Therefore y-intercepts must be different

(b ≠ -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
