Answer:
x=-5
Step-by-step explanation:
Vertical lines have the same x value all the time. They are of the form x=
Since it passes through the point (-5,-2) the x value must be -5
x=-5
The slope will be 2/1x (2 over 1)
The y-intervept is 1 (positive 1)

Answer:
c = 793/28
, d = -358/7
Step-by-step explanation:
Solve the following system:
{4 c + 2 d = 11 | (equation 1)
(7 d)/2 = -179 | (equation 2)
Multiply equation 2 by 2:
{4 c + 2 d = 11 | (equation 1)
0 c+7 d = -358 | (equation 2)
Divide equation 2 by 7:
{4 c + 2 d = 11 | (equation 1)
0 c+d = -358/7 | (equation 2)
Subtract 2 × (equation 2) from equation 1:
{4 c+0 d = 793/7 | (equation 1)
0 c+d = -358/7 | (equation 2)
Divide equation 1 by 4:
{c+0 d = 793/28 | (equation 1)
0 c+d = -358/7 | (equation 2)
Collect results:
Answer: {c = 793/28
, d = -358/7
