Write the missing numbers so that 2a + 5b = 30 One is done for you.

2a + 5b = 30 when a = 0 and b = __30

2a + 5b = 30 when a = 5 and b =

2a + 5b = 30 when a = 15 and b =

when a = 0

Substitute a = 0 into 2a + 5b = 30

2(0) + 5b = 30

5b = 30

b = 6

2a + 5b = 30

when a = 5

Substitute a = 5 into the above Equation

2(5) + 5b = 30

5b = 30-10

5b = 20

b = 4

when a = 15

Substitute a into 2a + 5b = 30

2(15) + 5b = 30

5b = 30-30

5b= 0

b = 0

Hope this helps.

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.
