Crank

Answer: The stuff in pink is the stuff I found based on the information given. The pink 40 comes from the blue 40. The reason that both of those angles are congruent is because they are alternate interior angles. This is the same reason about the angles whose measurements are 60. So the following things are true that we found that weren't already given: Angle PQR is 40 Angle PRQ is 60

Write an inequality to represent the graph.

lakkis [162]

Answer:

$y \leq -\frac{3}{4}x+2$

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>

$m=(-1-2)/(4-0)$

$m=-\frac{3}{4}$

step 2

<em>Find the linear equation of the solid line in slope intercept form</em><em> </em>

$y=mx+b$

we have

$m=-\frac{3}{4}$

$b=2$ ---> the y-intercept is given

substitute

$y=-\frac{3}{4}x+2$

step 3

Find the inequality

Remember that the solution is the shaded area below the solid line

therefore

The inequality is

$y \leq -\frac{3}{4}x+2$

y is less than or equal to negative three fourths times x plus 2
