Question

please answer these 5 questions:). (for a practice test graph photo up above) (question 9) use the graph to find the slope and y-intercept. (question 10) steve started with $50 and saved $20 each week. what is the equation when y represents the amount of savings and x represents weeks? how much will steve have after 4 weeks? (question 11) brittany started with $300 and spent $40 per week. what is the equation when y represents savings and x represents weeks? how much will brittany have after 4 weeks? (question 12) convert to slope-intercept form. -5/8x - 1/2y = 1 (question 13) convert to slope-intercept form. 9 + 3x = 6y

Answer 1

9. slope: 1/2 y-int: -4

10. y=20x+50

11. y=-40x+300

12. i dnt know

13.9/6+3/6x=y or 1.5+0.5=y

Explanation:

10. starts at 50, goes up by 20 per week

11. starts at 300, goes down 40 per week

13.

9+3x=6y

9/6+3/6x=y or 1.5+0.5=y
