Select the pair of equations whose graphs are perpendicular.
a.) 5x - 8y = 9
12x - 5y = 7
b.) 3x + 6y = 8
y = 3x - 8
c.) y = 2x - 7
x + 3y = 3
d.) 2y = -3x + 5
2x - 3y = 4

For which rational expression is -2 an excluded value of x?

Read the equations in the table below. then drag a description of the situation and a table to represent each equation. indicate whether each of the relationships is proportional or non-proportional.
