a. x= -7, y= 2

b. x= -4, y= 14

c. x= -3, y= 12

d. x= -7, y= -2

answer: a

2.

Find the x- and y- intercept of the line 2x + 3y = -18.

a. x-intercept is 18, y-intercept is 18

b. x-intercept is -6, y-intercept is 9.

c. x-intercept is 2, y-intercept is 3.

d. x-intercept is -9, y-intercept is -6.

amswer c

- Algebra: Check please!!! -
**MathMate**, Friday, May 13, 2011 at 12:20pmThey are both incorrect.

To find the x-intercept of the line

L : ax + by + c = 0

you would set y=0, (that is, where the line intersects the x-axis) and solve for x in :

ax + b(0) + c =0

To find the y-intercept, you would similarly set x=0, where L intersects the y-axis, and solve for y:

a(0) + by + c =0

Try the problems using the above methods and post your answers for checking if you wish.
