Given the points ( 8 , 5 ) and ( 4 , 4 )
The general slop-intercept form of the equation of the line is:
y = mx + c
where m is the slope and c is y-intercept
The slope will be calculated as following:
So, the equation of the line will be:
Using the one of the given points to find the value of c
Let , we will use the point ( 4 , 4 )
so, when x = 4 , y = 4
So, the slope - intercept equation of the line is:
