Answer:
(0, -2) (Answer B)
Step-by-step explanation:
Recall that the y-axis represents x = 0. The blue line crosses (intercepts) the y-axis when x = 0. The corresponding y-coordinate is -2. Thus, the y-intercept is (0, -2), or just -2.
If you are saying that the hypotenuse is 10 cm the you have to solve the following equation using the Pythagorean theory.
4^2 + b^2 = 10^2
16 + b^2 = 100
16 - 16 + b^2 = 100 - 16
b^2 = 84
Find
8x - 10
Combine like terms:
2x + 6x - 10
= 8x -10
