No need to solve for y. The value of y is given. See it?
To find x, plug the given value of y into
4x - 3y = 18.
4x - 3(-2) = 18
4x + 6 = 18
4x = 18 - 6
4x = 12
x = 12/4
x = 3
Answer: y = -2 and x = 3.

Answer:
4:5 cat to dogs
Step-by-step explanation:
Y-intercept is (0,2) so 4/5 would be the slope. Y=mx+b. y=4/5x + 2. This should help with your problem.
To compute the slope of a segment, given its endpoints
, you write

Given this formula, you have the four slopes:




Now, two segments are parallel if they have the same slope. So, AB and CD are parallel, because they both have slope 1, but BC and DA are not parallel.
This means that ABCD is not a parallelogram, because in parallelograms the opposite sides are parallel.
