Step-by-step explanation:
You would first need to find the slope. The Slope formula is m = (y2 - y1)/(x2 - x1). In your problem, (1, 2) could be (x1, y1) and (2, 5) could be (x2, y2). Substitute those values into the Slope formula to find m which is your slope.
The point-slope form of a line is y - y1 = m(x - x1). You already have (x1, y1) to substitute in so do that and also substitute in your m.
Let small cups = S
Large cups = L
They bought a total of 8 cups, so S + L = 8
Rewrite as S = 8-L (1st equation)
Then you also have
$3S + $5L = $30 (2nd equation)
Replace the S in the second equation with the first equation:
$3(8-L) + $5L = $30
Simplify:
24 - 3L + 5L = 30
Combine like terms:
24+2L = 30
Subtract 24 from both sides:
2L = 6
Divide both sides by 2:
L = 3
They bought 3 large cups
Since they bought a total of 8 cups, that means they bought 5 small cups ( 8-3=5)
Large = 3 cups, Small = 5 cups
