The slope-intercept form of line equation is $\"\"$ where m is the slope and b is the y - intercept of the line.

From the graph, two points are $\"\"$ , and the line intersect the y - axis at $\"\"$ , so y - intercept is 4.

First find the slope by using points $\"\"$ .

Substitute the values of $\"\"$ in the slope formula $\"\"$ . \ \ $\"\"$ .

Substitute the values of $\"\"$ in the slope-intercept form of line equation $\"\"$ .
