Answer:

a =70

Step-by-step explanation:

Angle a and 110 are supplementary, which means they add to 180 degrees

a+ 110 = 180

Subtract 110 from each side

a+110-100=180-110

a = 70

Answer:

a = 70°

Step-by-step explanation:

a and 110 form a straight angle, thus

a + 110 = 180 ( subtract 110 from both sides )

a = 70°

Simple...

you have: 8x-6y=1

You're trying to find m-->>using y=mx+b to re-write the line....

8x-6y=1

8x-6y=1
-8x -8x

-6y=-8x+1

$\frac{-6y}{-6} = \frac{-8x+1}{-6}$

y= $\frac{4}{3} x- \frac{1}{6}$

Your slope m= $\frac{4}{3} x$

Thus, your answer.
