The line passing through two points that are
Part (a)
The formula for the slope of a line is given below
Therefore, the slope of the line is 1/4.
Part (b)
The point-slope form of a line given by the formula
Substitute the values and find the equation of the line as follows
Part (c)
The slope-intercept form of a line has the general form of
Now, manipulate the equation in part (b) to convert it into the above form as follows
