Step-by-step explanation:
The exterior angle is the sum of the opposite interior angles of the triangle.
Therefore, m<D +m<C = 118°
=> 8y+3 +3y+5 = 118°
=> 11y = 118° - 8°
=> 11 y = 110°
=> y = 10°
m<D = 8y+3
= 8(10)+3 = 83°
m<C= 3(10)+5 = 35°
m<DEC = 180° -118° = 62°
Both the functions have the same slope which is 2.
V + 4 = -2(x - 1)
v + 4 = -2x + 2
v = -2x - 2. [ Final answer]

Answer:
y = 3x –5
Step-by-step explanation:
for slope-intercept form, y = mx + b
find the slope, m
(-8 -4)/(-1-3) = m
-12/-4 =m
3 = m
Substitute for m and use either coordinate for y and x to calculate b
4 = 3(3) + b
4 = 9 + b. Subtract 9 from both sides
4 –9 = b
–5 = b. Rewrite the equation with the calculated values for m and b
y = 3x –5
