Consider the following pair of equations:
y = −2x + 8
y = x − 1
explain how you will solve the pair of equations by substitution. show all the steps and write the solution in (x, y) form.

Okay so you use the bottom to substitute y so your equation will be:
x-1=2x+8 now solve for x
-x-8=-x-8 this is what you will be taking away from both sides
-1-8=2x-x this is your new equation now you just do basic math
-9=x this is x
Now that you found x find y by substituting x
y=2(-9)+8
y= -18+8
y= (-10) this is your y
Now to check your answer on the other equation
y= -9-1
y= (-10) this is now correct
(x,y)form is (-9,-10)

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
