From the location defined by completing Step 2, how many units up is line t?

Consider the line shown on the graph. Enter the equation of the line in the form y = mx where m is the slope.

• 4

• There is no flaw in Deshaun’s reasoning. Deshaun is correct.

• Deshaun was correct to add the exponents, but he needs to find the value of x before he can simplify.

Jenny is solving the linear equation 12 + 3x - 5 = 8x + 8 - 5x. Her final two steps are:

7 + 3x = 3x + 8

7 = 8

Select the statement that correctly interprets Jenny’s solution.

• The solution is x = 0.

• The solution is the ordered pair (7, 8).

• There is no solution since 7 = 8 is a false statement.

• There are infinitely many solutions since 7 = 8 is a false statement.

Martin knows that the relationship between the number of gallons of gasoline his car uses, g, and the number of miles he travels, m, is proportional. Which equation could represent this relationship?

• m = 26.5 + g

• m = 28g

• m = 31.5/g

• mg = 36
