A drawing is 6 inches wide and 8 inches long. it will be enlarge so that its measurements remain proportional, if the enlarged width is 15 inches what will be enlarged length

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

the equation of the line that passes through the points and has o form

if line passes through the points (-1, -3) and (2, 1), then

the equation in the standard form is
