If you mean 7 = 7x-3 then the perpendicular slope is -1/7 and the equation is y = -1/7x
If it passes through the origin
y = 3x
y = 0. You can get this from the slope-intercept equation of the line.
Perpendicular slope: -1/4 Perpendicular equation: y-0 = -1/4(x-3) => y = -0.25x+3
2-3
which equation has a slope of -1/2 and a graph that passes through (-3,4)?
If it passes through the origin
y = 3x
It is: y = -2x
That depends on the equation that it is perpendicular too which has not been given but both equations will meet each other at right angles.
y = 0. You can get this from the slope-intercept equation of the line.
Perpendicular slope: -1/4 Perpendicular equation: y-0 = -1/4(x-3) => y = -0.25x+3

The straight line equation is: y = 2x
y = - 3x
y=3x
y = x
