The equation of the line is 45x-104y= -5712

Explanation:

The slope of the line passing through (88,93) and (-120,3)

is m= (y_2-y_1)/(x_2-x_1)= (3-93)/(-120-88)= 90/208=45/104

Let the equation of the line in slope-intercept form be y=mx+c

:. y=45/104x+c. The point (88,93) will satisfy the equation .

, :. 93= 45/104*88+c or 104*93=45*88+104c or

104c=104*93-45*88or c=(104*93-45*88)/104 or

c= 5712/104=1428/26=714/13

Hence the equation of the line is y= 45/104x+714/13 or

104y = 45x+5712 or 45x-104y= -5712 [Ans]
