Given the graphed function , what is the slope of the line?

Given the slope is -4 and the y-intercept is 3, write a linear equation in slope-intercept form.

Which equation has a slope of 1 and a y-intercept of -9?

• y = -9x + 1

• y = 1/3x + 9

• y = x - 9

• y = -x - 9

Monica rents her bike to tourists for 2 dollars per hour. The deposit for the bike is 12 dollars. Which equation below matches this situation?

• y=12-2x

• y = 2x -12

• y = -2x +12

• y = 2x + 12

• y = -2x - 12
