Flura [38]

Answer:

Y = 2x + 1

Step-by-step explanation:

the slope is;

Change in "y"                     2

-------------------- (over) =     ------ or 2

Change in "x"                     1

The y-intercept is the point in the graph where a point in slope touches the y- axis and.

In this case the point is (0,1) so the y-intercept is 1.

Hope this helps!
