Which graph shows a slope of m = −1 / 2 and a y intercept of b = -4?

Letter D, because the y intercept is on -4 and if you look at the slope and use the method "Rise over Run" you can see that the rise is one and negative a half.

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.

answer: 2530
