The equations of four lines are given. Identify which lines are perpendicular

lines 2 and 4 are perpendicular

Step-by-step explanation:

if the slopes of two lines are opposed reciprocals, they are perpendicular. in this case the slope of line 2 is -1/2 and the slope of line 4 is 2 after you solve for y=mx+b form

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

answer: 1 and 3
