Question

Look at the following equations:

8P=12-2Q
Q+4P=6

Which statement is true about the lines graphed from the equations?

A. They coincide.
B. They are parallel.
C. They are perpendicular.
D. They intersect but are not perpendicular.

Answer 1

Anyone?

Answer 2

try to drawing the graph

Answer 3

to make a line we need two points

Answer 4

2P = 12 - 2Q
let Q = 1, then we substitute into the equation to obtain P

Answer 5

\[Q=1\rightarrow 2P = 12 - 2 \left( 1 \right)\]

Answer 6

Can you continue?

Answer 7

2P = 12 -2
2P = 10
P = 10/2
P = 5

Answer 8

I dont think so, still didnt get it

Answer 9

so we have a point (P, Q) = (1,5)

Answer 10

to draw a graph, we have to look for two point in the graph

Answer 11

ah alright

Answer 12

we already have one point, meaning we are now looking for another point

Answer 13

try for different Q values

Answer 14

Can you try it?

Answer 15

yeah thanks
