Look at the graph shown:

A coordinate plane is shown. A line passes through the y-axis at -1 and through the point 1 comma 2.

Which equation best represents the line?

y = 1 over 3. x − 1
y = 3x − 1
y = −x + 1 over 3.
y = 3x + 1

jhannybean · Answer

Use y = mx + b 

b= y intercept 

replace y with 2
replace x with 1

solve for m. 

Rewrite your function in slope intercept form y = mx +b
