Question

Choose the system of equations which matches the following graph.



3x + 4y = 24
3x + y = −3

3x + 4y = 24
3x − y = 3

3x − 4y = −24
3x + y = −3

3x − 4y = −24
3x − y = 3

Answer 1

Looking at the graph one line has slope ~ 2/3 and y-intercept = 6.
The other line has slope slope 3 and y-intercept = -3.

Answer 2

Why don't you rearrange your equations to solve for y?

Answer 3

if any of the equation equation can be represented like this\[{a_1\over a_2}\ne{b_2 \over b_2}\]then the equation can be represented through the graph like given:)

Answer 4

Choose the system in which the lines have slopes of 3/4 and 3.

Answer 5

what are a and b

Answer 6

Right, slope of 3/4 not 2/3

Answer 7

ax+by=c

Answer 8

a is the coefficient of x and b is the coefficient of y

Answer 9

Oh

Answer 10

So change the values to y=?

Answer 11

Use the fact that if the line is written in the form ax+by=c then it's slope is "the opposite of a over b"

Answer 12

So the slope of 3x+4y=24 is -3/4

Answer 13

Isn't opposite 4/3?

Answer 14

Take the third pair of equations. Solve for y.
y = 3/4 x + 6
y = -3x - 3
Does that match the data given? (No).
