A line passes through (3, 7) and (6, 9). Which equation best represents the line? (4 points) y = 3 over 2 x + 5 y = 2 over 3 x +
kotykmax [81]

Given two points, the equation of the line may be determined by,

y - y1 = ((y2 - y1) / (x2 - x1))(x - x1)

Substituting the given values,

y - 7 = ((9 - 7) / (6 - 3))(x - 3)

Simplification will yield to an answer of,

y = 2x/3 +5

Therefore, the answer is the second choice.

Could someone explain this to me?

You must solve for p, in order to solve for p you must move all the terms to equal p, so the equation is
2m + 2p = 16
first move the 2m, subtract the 2m from both sides
2m + 2p = 16 \\  - 2m \:  \:  \:  \:  \:  \:  \:  \:  - 2m
the 2m and -2m cancel out and now your equation looks like
2p = 16 - 2m
now to leave p by itself you must divide by 2 on both sides as the 2 is being multiplies on the p (opposite)
\frac{2p}{2}  =  \frac{16 - 2m}{2}
now to put the answer is simplest form your answer is
p = 8 - m
which is the first answer choice

Answer:

x = 7/4 = 1.75

Step-by-step explanation:

Hello - so you don't seem to have shown what the calculator screen displays, however I can assume it will show a graph of the two lines, and their intersection point. The x-co-ordinate of this intersection point is the solution to the equation.

As I can't see the calculator, I will also show you how to work out the solution for x:

3x - 1 = 6 -x

4x -1 = 6

4x = 7

x   = 7/4  = 1.75
