The answer would be 42° because a triangle equals 180° and you know 2 angle measurements, 48 and 90.
48 + 90 = 138
180 - 138 = 42°
(You know one angle is 90° because supplementary angles equal 180°)
Slope:-6/5
We can find the rise over run by solving for and simplifying:-6-6/-8-(-18)=-12/10=-6/5
When it asks for the image, that means what are your new coordinates after doing the rules they give you. In this, the rule is to subtract 2 from your x value and subtract 3 from the y value. So you subtract 2 from 0 and subtract 3 from 3. This will give you the values to use for the x and y of your answer:)
