Question

What is the slope of the line that contains the points (4, 3) and (2, 7)?

OA-1
B. -5
C. -2
OD. -

Answer 1

B. -2

Explanation:

To find a slope of a line, you have to identify x and y variables:

• (4, 3) => (x1, y1)
• (2, 7) => (x2, y2).

We use the formula;

m = ∆y/∆x

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

• m is slope

Substitute the values into the formula above.

m = (7 - 3)/(2-4)

= 4/-2

= -2

Therefore, the slope of the line is passing through points (4,3) and (2,

7) is -2.
