i don't get the first slide
Step-by-step explanation:
You can find the x and y intercepts by plugging 0 in for each of the variables
(0)=-7x-1
1=-7x
x=-1/7
your x- intercept is (-1/7,0)
y=-7(0)-1
y=-1
your y-intercept is (0,-1)
I believe the answer is 142 degrees.
38 degrees and 7 are adjacent, meaning adding them up will get you 180 degrees. 180-38=142, so 7 is 142.
Number 7 and 5 are corresponding, so they are equal.
This means that 5 is 142 degrees.
(I think)
So the simplified version would be,

The degrees I'm unaware of...
