Write the equation of this line in slope-intercept form.

*y* = *x* +

A linear equation of a slope-intercept form *y* = m*x* + b , m is the slope and b is the *y*-intercept.

From the graph, we can see that the slope is 2, and the* y*-intercept is (0, -1).

The equation of this line is therefore *y* = 2*x* – 1.
