What mistake did this student make? 1. The 2nd equation should have been added to the 1st equation, not subtracted

2. The 2nd equation should have been multiplied by 3

3. The 1st equation should have been multiplied by 2

4. Neither equation is in standard form

3. the 1st equation should have been multiplied by 3

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
