Which graph best represents the solution to the system of equations shown below?

y = −4x − 19
y = 2x − 1

Answer 1

Its B

Explanation:

x = 3

y = 7

Answer 2

see below

Explanation:

It is convenient to choose a feature of the equations that will identify the appropriate solution.

Both equations are in slope-intercept form, and all graphs show lines with slopes of -4 and +2.

The first equation has a y-intercept of +19. That value is not shown on any of the graphs.

The second equation has a y-intercept of -1. The only graph with a line through the point (0, -1) is choice C. (It also correctly graphs the first equation.)
