The y-intercept is found when x is set to 0.
Set x to equal 0 for both equations:


Divide both sides by -2:

The y-intercept of this equation is 3, so the first line does not have the y-intercept of -2.
-


Divide both sides by 2:

The y-intercept of this equation is -1, so the second line does not have the y-intercept of -2.
Neither line has a y-intercept of -2.
Cosine Rule again:-
cos A = (9^2 - 6^2 - 14^2) / (-2*6*14)
= 0.8988
m < A = 26 degrees
Answer:
D. I got it right on my quiz.
Step-by-step explanation:
Example C: w cubed z, +, 5, z squared, minus z squared, +, 6 ..... For example, 2x + 1 = 7x and 10x minus 9y minus z = 3 are linear equations, but x, +, y ...
