Answer:
y = -4x + 1
Step-by-step explanation:
The line passes through points (-5,21) and (-4,15)
Slope(m) = change in y ÷ change in x
m = 
m = 
= -36/9 = -4
Taking another point (x,y) on the line and comparing it with point (4,-15):
-4 = 
Cross multiplying gives:
y + 15 = -4x + 16
y = -4x + 1
Answer:54
Step-by-step explanation:
let's firstly convert the decimal to a fraction, namely a rational.
so we have one decimal, thus let's use 1 zero at the denominator and lose the dot on the numerator.
so then, what rationals are between -8/5 and +8/5? well, a huge amount hmmm let's pick two.

X=113
The angle inside the triangle by the 53 is also 53.
We know triangles have 180 degrees so the other angle is 180-53-60=67
X is the supplementary angle to the 67 so x=113
