Question

Which equation is a point slope form equation for line AB ?

Answer 1

Answer:

C) y + 2 = -2(x - 5)

Step-by-step explanation:

The given graph passes through the point A (1, 6) and B (5, -2)

Now let's find the slope of the given line.

Here x1 = 5, y1 = -2, x2 = 1 and y2 = 6

Slope(m) = (y2 - y1)/(x2 - x1)

= (6 -(-2))/(1  - 5)

= 8/-4

Slope (m) = -2

The equation of line is  y - y 1 = m (x - x1)

y - (-2) = -2(x  - 5)

y + 2 = -2(x - 5)

Answer C) y + 2 = -2(x - 5)

Thank you.
