Step-by-step explanation:
Equation of a line:
The equation of a line that passes through point , in point-slope form is given by:
In which m is the slope.
Finding the slope:
To find the slope of a line, we need a pair of points. The slope is given by the change in y of these points divided by the change in x.
In this question:
Points (2,2) and (4,6).
Change in y: 6 - 2 = 4
Change in x: 4 - 2 = 2
Slope:
So
I can consider any of these two points , i will use (2,2). So
