Answer 1

first find the y-intercept.

Answer 2

then do rise/run from the y-intercept to find the slope

Answer 3

Take 2 points from the graph that represents the line
(0,1) (1,3)
Find the slope 1st
Slope = Y2-Y1/X2-X1
Slope = 3-1/1-0
Slope = 2/1
Slope = 2

Now we know the y intercept is when x = 0
When x was zero we had y equal to 1 so Y intercept is 1
Y= 2x + 1
Would be the equation
Make sense?

Answer 4

yeah thanjs
