Line perpendicular to the line that goes through (0,0) and (3,2)
KonstantinChe [14]
Since the first line passes thru the origin, you can read off its slope from the coordinates of the other point (3,2):  the slope is m = 2/3.

A line perpendicular to the first has slope -3/2, the negative reciprocal of 2/3.

Thus, the perpendicular line is    y = (-3/2)x + b.  Subbing 0 for y and 0 for x, we get b = 0.  Therefore, the equation of this new line is y = (-3/2)x.

Please help me answer this for my grade !! <br><br> I will give braisnlt
skelet666 [1.2K]

Step-by-step explanation:

2x+3y=23 2x+3.7=23 2×1 + 3×7 = 23

3y= 23 2×+21= 23 2 + 21 = 23

23÷3 = 7 2x= 23-21

y=7 2x= 2

x= 1

5x+3y=17 5×4+3y=17

5x=17+3 20+3y=17

5×=20 20=17+3y

14÷5 = 4 20=20+y

x=4 y=20-20

y=0
