3x - 4y = 28

4x + 10y = 20

What is the slope-intersect form of each equation? Compare to describe the graph of the system.

Y=3/4x - 7

y=-2/5x - 2

3x - 4y = 28

-4y = - 3x + 28

y = (-3/-4) x + (28/-4)

y = 3/4x - 7 ... slope is 3/4 ... y int is (0,-7)

4x + 10y = 20

10y = - 4x + 20

y = (-4/10) x + (20/10)

y = - 2/5x + 2 ... slope is - 2/5 ... y int is (0,2)

so ur 2 equations in slope intercept form are:

y = 3/4x - 7 and y = - 2/5x + 2

These equations will have one solution, (180/23, - 26/23) ... they are neither parallel or perpendicular.
