Y=2

first you would plug x into the equation:
2(4)+3y=14 which then gives you:
8 + 3y =14
then you would subtract by 8 on both sides leaving you with :
3y=6
then you divide by 3 on both sides and get Y=2

Answer:

Step: Solvex=4for x:

x=4

Step: Substitute4forxin2x+3y=14:

2x+3y=14

(2)(4)+3y=14

3y+8=14(Simplify both sides of the equation)

3y+8+−8=14+−8(Add -8 to both sides)

3y=6

3y

3

=

6

3

(Divide both sides by 3)

y=2

Answer:

x=4 and y=2

The correct answer is A) y - 4 = -2/5(x + 1)

We know this because of the basic form of point slope form, which is shown below.

y - y1 = m(x - x1)

In which the point (x1, y1) is on the graph and m is the slope. When counting the slope, we can see that it is -2/5 based on the fact that for every two spaces the graph travels down, it moves to the right five. This eliminates options C and D and gives us this form to work with.

y - y1 = -2/5(x - x1)

Now we have the point (-1, 4), so we can plug this in to match it with a formula.

y - 4 = -2/5(x - -1)

y - 4 = -2/5(x + 1)
