What is the slope-intercept form for each equation in this system? compare the slopes and y-intercepts to describe the graph of the system. 3x - 4y = 28 4x + 10y = 20 a) y = 3 4 x − 7; y = −2 5 x + 2; one line b) y = -3 4 x − 7; y = −2 5 x + 2; parallel lines c) y = 3 4 x − 7; y = 2 5 x + 2; intersecting lines d) y = 3 4 x − 7; y = −2 5 x + 2; intersecting lines

We can compare slopes and y-intercepts. The first equation has m=3/4 and b=7. The second has m=-2/5 and b=2. They are intersecting lines.

Step-by-step explanation:

These equations are in the standard form of a line. We can convert to the slope-intercept by solving for y.

We can now convert the second equation.

We can compare slopes and y-intercepts. The first equation has m=3/4 and b=7. The second has m=-2/5 and b=2. They are intersecting lines. This eliminates A and B. The answer based on the information given is likely D.
