Answer:
For y=x-3. (0,2) the equation is y=x+2
For y=3-x. (0,2) the equation is y=2-x
For y=3x+1. (0,3) the equation is y=3x+3
For y=-1/2x+4. (0,1) the equation is y=-1/2x+1
Step-by-step explanation:
How I got my answers:
For y=x-3: the gradient is 1 because we do not have anything before x.
For the points given for example (0,2) x is zero and y-intercept is 2. same for the rest of the points.
Now you can write your equation in the form y=mx+b
where m is your gradient, and b is the y point. So you say y=1x+2 for the first one. Do the same for the rest. Remember 1x is the same as x so you can leave out 1.
You can comment if you did not understand my explanation because this explained how you can do it.
