What is the slope of the first equation?

triciaal · Answer

given the line in slope intercept form you can read off  the slope , m 
for perpendicular lines the slope is -1/m 
this line passes through (-4, -3) substitute and find b, the intercept
now you have any point (x, y) the slope, m and the intercept, b you can write the general equation for the perpendicular line
