Write the equation in slope-intercept form of the line parallel and line perpendicular to the given line.
y=4x+7 (-2,-9)
2x-5y=10 (3,-7)
3x+4y=16 (12,-5)

I don’t know if this is right but for
Y=4x+7 your m would be 4/1 and where you begin would be 7
2x-5y=10: you would take 10 and divide it by the two numbers in front (10 divided by 2= 5) (10 divided by -5=-2)
For 3x+4y=16 you would do the same you did for the last equation (16 divided by 3= 5.3) (16 divided by 4=4
