2/1
There are multiple.
ANSER IS 24
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
