Answer:
y is less than or equal to negative three fourths times x plus 2
Step-by-step explanation:
step 1
Find the slope of the solid line
we have the ordered pairs
(0,2) and (4,-1)
<em>Find the slope m</em>
step 2
<em>Find the linear equation of the solid line in slope intercept form</em><em> </em>
we have
---> the y-intercept is given
substitute
step 3
Find the inequality
Remember that the solution is the shaded area below the solid line
therefore
The inequality is
y is less than or equal to negative three fourths times x plus 2
