Question

The line passing through the points (-2: 1) and (1: 4) has the same angular coefficient as the line passing through the points (1-2) and (3: p) Find the value of p

Answer 1

Explanation:

The angular coefficient is also referred to as the slope of the line.

Given that the slope of the lining joining these pair of points are the same:

• (-2, 1) and (1, 4)

,

• (1, -2) and (3, p)

Then:

`(4-1)/(1-(-2))=(p-(-2))/(3-1)`

We solve the equation for p:
