Help pls all the questions i dont get it :(​

A. The graph is not proportional, although it has a consistent slope, it does now go through the point of origin or (0,0). The equation of a proportional line is y=kx, so the y-intercept must be at (0,0).

B. Slope is found by  , from 1 point to the next, the y-value (rise) increases by 2 and the x-value (run) increases by 1, giving us a slope of 2.

C. The y-intercept is the lines point of intersection with the y-axis. In the graph, this point is (0,10).

D. y = mx + b is the slope-intercept form where m is the slope and b is the y-intercept, the slope (m) is 2 and the y-intercept (b) is 10. y = 2x + 10

E. The equation is not proportional because the b value is 10 rather than 0.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
