Applications Slope Intercept

A real estate agent earns a base salary of $1250. For every house, h, she sells, she receives $750.

Which equation could be used to determine the amount of money, m, she would have after selling any number of houses, h?

• m = 1250 + 750h

• m = 750 + 1250h

• 1250 = 750h + m

• 750 = 1250m + h

Which value is the slope in the equation: y= 4x + 2

• 4

• 2

Zara made an initial deposit to a bank account and then added a fixed amount every week. The table shows the money in her account. Write an equation in slope-intercept form to represent the situation.

• y = 30x + 100

• y = 20x + 120

• y = 120x + 120

• y = 50x + 100

Which is the graph with the slope -1/3 that passes through the point (0,5)?

• y = 5x -1/3

• y = -1/3x + 5

• y = -1/3x - 5/3

• y = 5x - 5/3

What is the equation of the line that passes through (-2, 3) and has a slope of 4?

• y = -2x + 3

• y = 4x - 2

• y = 4x + 3

• y = 4x + 11

Given the two points: (0, 6) and (6,18), write the equation of the line.

• y = 2x + 6

• y = 1/2x + 6

• y = 1/3x + 6

• y = 3x + 6
