Help with these problems

Answer 1

The graphs are attached in order :) (pay attention to the labels, if you're confused)

11. m = 1, b = -4

13. m =
`(5)/(3)`, b = 2

15. m =
`-(7)/(2)`, b = 0

17. y =
`-(3)/(2)x` + 5

18. y = 2x - 2

Explanation:

y = mx + b

m = slope

b = y-intercept

11. y = x -4 (there is an invisible 1 infront of x)

m = 1

b = -4

13. y =
`(5)/(3)x` + 2

m =
`(5)/(3)`

b = 2

15. y =
`-(7)/(2) x`

m =
`-(7)/(2)`

b = 0

17. Find slope using (0,5) and (4,-1)

m =
`(y_2-y_1)/(x_2-x_1)=(-1-5)/(4-0) =-(6)/(4)=-(3)/(2)`

y =
`(3)/(2)x` + 5

18. y = 2x - 2

Hope this helps!
