Question
Determine, without graphing. whether the two given lines are parallel, perpendicular, or neither. Check your answer by graphing both lines on a calculator or by hand.$2 x-5 y=40$$-4 y=10 x+10$
Step 1
The first equation is $2x - 5y = 40$. We can rearrange this to solve for y: $-5y = -2x + 40$ $y = \frac{2}{5}x - 8$ So, the slope of the first line (m1) is $\frac{2}{5}$. Show more…
