Question

What is the equation in point slope form of the line that passes through the point (3, 1) and has a slope of –2 ?

Drag and drop the appropriate number, symbol, or variable to each box.

Answer 1

y – 1 = -2 (x – 3)

Explanation:

i had this on my quiz and got It right

Answer 2

A point slope form of equation has a general form of:

y – y1 = m (x – x1)

From the given data, the variables are:

y1 = 1

m = -2

x1 = 3

Therefore:

y – 1 = -2 (x – 3)
