Answer:
y = 4/3x -7
Explanation:
You want the slope-intercept form of the equation for the line shown on the graph.
Points
Points are marked on the graph, which can aid you in finding the slope.
One of them is on the y-intercept at (0, -7).
The next one to its right is up 4 units to y = -3, and right 3 units to x = 3. Its coordinates are (3, -3).
The slope is the ratio of rise to run:
m = rise/run = +4 units / (+3 units) = 4/3
Now you know the slope is m = 4/3, and the y-intercept is b = -7, so you can put these in the slope-intercept form equation:
y = mx + b
y = 4/3x -7
