Answer:
See below for answers
Step-by-step explanation:
Problem 1
[tex](x_1,y_1)\rightarrow(0,20)[/tex]
[tex](x_2,y_2)\rightarrow(2,40)[/tex]
[tex]m=\frac{y_2-y_!}{x_2-x_1}=\frac{40-20}{2-0}=\frac{20}{2}=10[/tex]
[tex]y=mx+b[/tex]
[tex]y=10x+b[/tex]
[tex]20=10(0)+b[/tex]
[tex]20=b[/tex]
[tex]y=10x+20[/tex] <-- Answer
Problem 2
See attached graph and recreate it on paper. It's helpful to use the y-intercept and x-intercept to make the line.
