2/1

There are multiple.

The answer is 2

It could be y=2x and an incorrect equation would be y=2x -3

Incorrect- 0x+3

Correct-Y=2x

The correct equation is y=2x incorrect-y=x-2

Multiple as long as they match up

Correct y=2 incorrect y=4

Correct: y=2x

Incorrect: y=0x+3

Any positive slope could be argued (since axis scales are not necessarily known) with a y-intercept of 0. So any equation of the form y = mx, where m>0. Equations that wouldn’t work are of the form y = mx + b, where m is less than or equal to zero and/or b is not equal to 0.

Incorrect: y=x+2

Correct: y=2x

Incorrect: y= 5x-1

Correct: y=2x

I totally agree with your statement.

Incorrect: y=3+x

Correct: y=2x

👍- 2

👎- 0x+5

Correct y=2x

incorrect- y=3+x

correct-y=2x

Incorrect : y=3+x

Correct : y=2x
