I have to solve these using area models: 1. 30 x 24
2. 40 x 43
3. 30 x 37
4. 20 x 26
5. 50 x 35

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
