Answer:
slope is -5
Step-by-step explanation:

This equation is in slope-intercept form:

where m is the slope and b is the y-intercept.
In the given equation, the slope is -5 and the y-intercept is 1.
Answer: C) 40 degrees
Step-by-step explanation:
if the total angle is 70 degrees and part of it is 30 degrees
then the other part is x degrees
30 + x = 70
30 - 30 + x = 70 - 30
x= 40

Answer:
y = 38
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the angles in the large outer triangle, then
x + 46 + 78 = 180
x + 124 = 180 ( subtract 124 from both sides )
x = 56
Consider the 3 angles in the smaller inner triangle, then
y + x + 86 = 180 , that is
y + 56 + 86 = 180
y + 142 = 180 ( subtract 142 from both sides )
y = 38
