What does the graph of -3x-5y≥20 look like?

a. dashed boundary line, shaded above the line

b. dashed boundary line, shaded below the line

c. solid boundary line, shaded above the line

d. solid boundary line, shaded below the line

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
