We can use the formula y2-y1/x2-x1 to find the slope.
1. 2-(-15)/12-5 gives us 17/7. The slope is 17/7.
2. -5-(-20)/6-(-18) gives us 15/24. We can simplify this to 5/8. The slope is 5/8.
3. -19-(-19)/-17-(-18) is 0/1. The slope is 0.
4. -17-3/-11-(-1) is -20/-10. The slope is 2.
<span>With five houses every three hours, Brianna will paint 20 houses in 12 hours. 12 hours / 3 hours = 4 'rounds'. 5 houses * 4 rounds = 20 houses.
With three houses every four hours, Nicholas will paint 9 houses in 12 hours. 12 hours / 4 hours = 3 'rounds'. 3 houses * 3 rounds = 9 houses.
So Brianna will paint 20 - 9 more houses than Nicholas, or 11 houses more.</span>
Chase collected $27.34. Sydney collects $9.83 more than Chase.
27.34 + 9.83 = 37.17
$37.17 is how much Sydney collected. Since Ally collected 4 times as much as Sydney, you can multiply what Sydney collected by 4.
37.17 · 4 = 148.68
Ally collected $148.68
