Question

Please Help!!!!!!!!!!!!

Answer 1

I need help finding the equation of the line through (1,2) and the point of intersection of x+2y=3 and 2x-3y=-1

Answer 2

so you have system of equations to solve for point:
x + 2y = 3
2x - 3y = -1

You would need to solve for x and y. better start by isolate x in first equation.

Answer 3

Okay. Thanks! After I solve for x and y, what do I have to do next?

Answer 4

For x I got 11/7 and for y I got 5/7

Answer 5

Whoops. I checked over my work and I got that x=1 and y=1

Answer 6

Okay, so I tried to find the slope of the line that contains the points (1,2) and (1,1) but it is undefined since I get (1-2)/(1-1)

What do I have to do now? Does that mean that the line is undefined as well?

Answer 7

yep x=1 and y=1.

If your slope is undefined, that mean line that pass through these points is vertical.

Answer 8

so your line is vertical

Answer 9

Ohhh!! Okay. But how do I find what x equals?
