We know a is perpendicular l and that perpendicular means 90 degrees. Using corresponding angles, we know that angle 3 also is 90 degrees. Using corresponding angles again, was know angle b is 90 degrees. Since 90 degrees is the same thing as perpendicular this would mean that line b is perpendicular to line m.

Are the graphs of the lines in the pair parallel? Explain. y=2\3x-17 4x-6y=-7

Papessa [141]

y=2\3x-17and 4x-6y=-7 implies - 6y= - 4x -7, and then y= (-4/-6)x +7/6 and so
y=2/3x+7/6

but when we have y=ax+b and y=a'x+b', the two lines are parallels if a=a', in our case 2/3=2/3 the lines are parallel
