Find the equation of the line (ax+by+c=0) using the ff. properties.

y-intercept=4 and parallel to x-axis

y-intercept=-3 and perpendicular to the line y=x


Sagot :

parallel to x axis means m=0, y int (b) = 4 so line is y=4

y int (b) = -3 and perpendicular to the line y=x so m=-1

y=-x-3 or x+y+3=0
