Answer:
The solution of a system of linear equations is:
D. The values of the variables that satisfy both equations.
8(4a+2b)
The equivalent is 32a+16b (B)
(0,30), (1,20)
(20-30)/(1-0) = -10/1 = -10 slope
We know y intercept is 30
Equation: y = -10x + 30
The second to last one, looks like a really tall speed bump
