help with these problems

Answer:
The graphs are attached in order :) (pay attention to the labels, if you're confused)
11. m = 1, b = -4
13. m = [tex]\frac{5}{3}[/tex], b = 2
15. m = [tex]-\frac{7}{2}[/tex], b = 0
17. y = [tex]-\frac{3}{2}x[/tex] + 5
18. y = 2x - 2
Step-by-step 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 = [tex]\frac{5}{3}x[/tex] + 2
m = [tex]\frac{5}{3}[/tex]
b = 2
15. y = [tex]-\frac{7}{2} x[/tex]
m = [tex]-\frac{7}{2}[/tex]
b = 0
17. Find slope using (0,5) and (4,-1)
m = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{-1-5}{4-0} =-\frac{6}{4}=-\frac{3}{2}[/tex]
y = [tex]\frac{3}{2}x[/tex] + 5
18. y = 2x - 2
Hope this helps!
