What is the equation of the graphed linear model? y = x +
graph:

One point on the line is (1,3) and another point is (9,11).

Find the slope of the two points on the line.



Now, let's make our equation in the form of y = mx + b, where m is the slope and b is the y-intercept.

We now have y = 1x + b

Plug in a point and solve for b.

y = 1x + b

3 = 1(1) + b

3 = 1 + b

b = 2

The equation is y = x + 2.
