For each equation, find y when x = -3. Then find x when y = 2.

y = 6x + 8

For each equation, find y when x = -3. Then find x when y = 2.

y = \frac{2}{3}x

For each equation, find y when x = -3. Then find x when y = 2.

y = -x+5

For each equation, find y when x = -3. Then find x when y = 2.

y = \frac{3}{4}x-2\frac{1}{2}

For each equation, find y when x = -3. Then find x when y = 2.

y = 1.5x+11

Match each graph of a linear relationship to a situation that most reasonably reflects its context.

True or false: The points (6,13), (21, 33), and (99, 137) all lie on the same line. The equation of the line is y = \frac{4}{3}x + 5.

Here is a linear equation: y = \frac{1}{4}x + \frac{5}{4}.

Are (1, 1.5) and (12, 4) solutions to the equation?

Here is a linear equation: y = \frac{1}{4}x + \frac{5}{4}.

Find the x-intercept of the graph of the equation.

Find the coordinates of B, C, and D given that AB = 5 and BC = 10.
