They are vertical angles, thus they are equal to each other:
5x + 12 = 6x - 10
22 = x
x = 22
The answer is y=(1/2)x -5
You are given the slope and a core donate pair so you plug them in to the equation. 2=x. -4=y. And (1/2)= m
Then work out like a one step equation
Y = x^2 cos x
y' = x^2 * -sin x + cos x * 2x
= 2x cos x - x^2 sin x
= x ( 2 cos x - x sin x)
Probability of an event= number of ways an event can occur / total number of possible outcomes.
Probability = 6/12 = 0.5
