Which of the following is a point-slope equation of a line that passes through the points (-1, 4) and (8,-2)? A. y-4= -3/2(x+1)
B. y-4= -2/3(x+1)
C. y-4= 2/3(x+1)
D. y-4= -2/3(x-1)​

B

Step-by-step explanation:

We want to find the point-slope equation of a line that passes through the points (-1, 4) and (8, -2).

Point-slope form is given by:

Where m is the slope and (x₁, y₁) is a point.

So, let's find the slope of the line first. We can use the slope formula:

We can choose (-1, 4) as our point. So, (x₁, y₁) = (-1, 4).

Substitute:

Simplify:

Therefore, our answer is B.

b. x- 48 =120

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
