Which linear equation best describes the graph above?

y = 3/5x + 4

y = 5/3x + 4

y = 3/5x - 6.5

y= 5/3x + 6.5

Answer explanation

We can see that the y-intercept (b) is 4. From there, using rise/run, we can see that we go up 3 and over 5, making the slope 3/5. Substituted into the equation y=mx+b, we would have the equation y=3/5x+4.

Carlos bought a video game. He made an initial payment of $75 to the store, and he will pay $5 each month until the game is paid off.

Which equation represents the relationship between m, the number of monthly payments Carlos has made, and t, the total amount that Carlos has paid the store?

t = 75m + 5

t = 5m - 75

t = 75m + 80

t = 5m + 75
