The slope formula is <span>m = (y2-y1) / (x2-x1)</span>
The difference between y is 9-0=9
The difference between the x is -3-8=-11
the answer is a
make sure you do y2-y1 and x2-x1 or y1-y2 and x1-x2, but dont do y1-y2 and then x2-x1. They should match up.
Answer:
∠ b = 12°
Step-by-step explanation:
Complementary angles sum to 90°, thus
a + b = 90 ← substitute a = 78
78 + b = 90 ( subtract 78 from both sides )
b = 12
That is ∠ b = 12°
