Answer:
y=3x-5
Step-by-step explanation:
Slope intercept form is y=mx+b
m represents slope
b represents y-intercept
In the picture, 3 replaces m, so 3 is the slope of the line.
When (2,1) and (5,10) are graphed, the line intercepts -5 on the y axis.
-5 is the y-intercept.
So, (2,1) and (5,10) in slope-intercept form is

Answer:
Shifted left by 2 units
Step-by-step explanation:
When you have a function (say f(x)), you can translate it left or right by replacing what's inside the function. In this case it is shown that the x in f(x) is replaced with x+2 in g(x). Therefore:
Rewriting g(x) like this shows that there is a +2 in the f(x). Whenever there is a number being added inside the function, then the graph is shifted left that many units (and vice versa for subtraction). So in this case since 2 is being added inside the function the graph will be translated left 2
