The slope of the line below is -2. Which of the following Is the point-slope form of a line? (4,-8)

A. y+8=-2(x-4)

Step-by-step explanation: Point-slope form is y-y₁=m(x-x₁), in which you only substitute three values: the slope, and the x and y coordinate. So, since the slope is -2, you replace it with m. And, if the point is (4, -8), you would substitute the 4 in for x₁, but the -8 is a little more complicated because it is negative. Basically, the negative and the minus sign cancel out and it becomes a plus sign.

Hope this helped! Good luck!

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.

3; 9 is 8 to -4
