Answer:

y > 4/3x + 4

Explanation:

Slope-intercept form is y = mx + b. Since this is an inequality, you need to find out what sign you are using first. A dotted line means that those points are not included in the solution, and the shaded region to the left lets you know that you are using a greater than sign.

Your equation would now be y > mx + b.

To find the slope (m) you use the equation (y2 - y1)/(x2 - x1) or rise/run, so using the coordinates (-3,0) and (0,4), you can plug these numbers into the slope equation and get the slope, which is 4/3. Now you have y > 4/3x + b

Then to find the y-intercept (b), you have to look on the graph for what y is when x = 0, represented as (0,y). On the graph you can see that when x = 0, y = 4 so your y-intercept is 4.

This leaves you with: y > 4/3x + 4
