Question

Find the equation of this line.y =x +Enter

Answer 1

First, we have to find the slope.

$m=\frac{y_2-y_1}{x_2-x_1}$

Let's replace the points (0,1) and (4,3).

$m=\frac{3-1}{4-0}=\frac{2}{4}=\frac{1}{2}$

The slope is 1/2.

Also, the y-intercept is 1, according to the graph.

Therefore, the equation is

$y=\frac{1}{2}x+1$
