➷ Pick any two sets of values
I will just select the first two:
(-2,-9) , (1,3)
First, you need to find the slope
slope = difference in y values / difference in x values
slope = (3-(-9)) / (1-(-2))
slope = 12 / 3
slope = 4
Substitute the slope into the general equation of a line form with one of the coordinates:
3 = 4(1) + c
3 = 4 + c
c = -1
The equation would be y = 4x - 1

<h2>Answer: </h2>
<u>In a right triangle, Relation of base and hypotenuse is cosine</u>.
cos40° = 10/h
0.76604 = 10 × h
0.76604h = 10
h = 10/0.76604 = 13.05units.
Answer:
A
Step-by-step explanation:
y = x² - 6x - 4
(x - 3)² - 3² - 4 = 0
(x - 3)² - 13 = 0
(x - 3)² = 13
x - 3 = ±√13
x = 3 ± √13
The fraction is already in its simplest form, can not be further simplified
