Bob has $150 in his savings account and saves $40 per month.  Which equation represents the amount Bob has in his account after x months?

• y = 150 + 40

• y = 40x + 150

The mathematics department sponsors Math Family Fun Night every year. In the first year, there were 35 participants. In the third year there were 57 participants. Write an equation in slope-intercept form that represents this data.

• y = 11x + 24

• y = x + 35

• y = 3x + 57

• y = 11x + 35

A magazine offers an online subscription that allows pay to view archived articles. To view 30 archived articles, you pay $49.15. To view 33 archived articles, you pay $57.40. Use the two points given to create an equation in slope-intercept form. \frac{y_2-y_1}{x_2-x_1}

• y = 30x + 49.15

• y = 2.75x + 35.40

• y = 33x + 57.40

• y = 2.75x + 49.15
