Answer:
m∠1 +m∠8 = 90°
Step-by-step explanation:
There is no necessary sum relation between angles 3 and 5 or angles 7 and 10. The only thing you can say about those angle pairs is ...
∠3 + 90° = ∠5
∠10 +90° = ∠7
Angles 8 and 9 are congruent, so don't have any necessary sum.
Angle 1 is congruent with angle 3, which is complementary to angle 8, so we must have ...
m∠1 +m∠8 = 90°
Answer:
slope = difference in y / difference in x
slope = (9 - -9) / (9 -0)
slope = 18 / 9
slope = 2

Answer:
<u>y = x + 7</u>
Step-by-step explanation:
Calculate the slope of a line that passes through (-2,5) and (1,8). The slope is the Rise/Run between the 2 points:
Rise = (8 - 5) or 3.
Run = (1-(-2)) = 3
Rise/Run, the slope m, is 3/3 or 1.
The equation can be written as y = 1x + b.
We need to find a value of b that forces the line though both points. Do that by entering one of the two points into y = 1x + b and solve for b. I'll use point (1,8)
y = x + b
8 = 1 + b
b = 7
The equation becomes <u>y = x + 7</u>
