The bottom one
Basically the question is what graph shows a number below or equal to -1
Answer:
<ABC=50
<EDB=30
<DFC=60
Step-by-step explanation:
<ABC=50 BECAUSE ANGLE SUM PROPERTY
90+40+50=180
<EDB=30 BECUSE ANGLE SUM PROPERTY
100+50+30=180
<DFC=60 BECAUSE ANGLE SUM PROPERTY
30+90+50=180

we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

Step 1
<u>Find the slope of the given line</u>
we have

Solve for y
Divide by
both sides


the slope of the given line is 
Step 2
<u>Find the slope of a line that is perpendicular to the given line</u>
we have



substitute the value of m1

therefore
<u>the answer is</u>
the slope is
