Please tell me where to graph this (its about slope)

When it come to coordinates (x,y) x comes first then y. And when it comes to fractions rise/run rise is your numerator and run is your denominator.

y = 1/2x + b

3 = 1/2(4) + b

3 = 2 + b

1 = b

y = 1/2x + b

Hope this helps

your graph should look like this

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
