Step-by-step explanation:
Let’s have two points (5,10) and (15,20)
1. Let’s find the slope of these two points
Mathematically, the slope can be calculated using the formula;
m = (y2-y1)/(x1-x2)
So m = (20-10)/(5-15) = 10/-10 = -1
The error here is the formula used in calculating the slope
The formula should be;
m = (y2-y1)/(x2-x1) and not x1-x2
2. To calculate the slope correctly, we have;
m = (y2-y1)/(x2-x1)
So the slope will be;
m = (20-10)/(15-5) = 10/10 = 1
In the point slope form, the equation can be represented as;
y-y1 = m(x-x1)
Let’s use the point (5,10)
y- 10 = 1(x-5)
The above is the point slope form
using one of the points and the correct slope of the line
