Y'all can you answer these? 8th grade algebra 1-10 Q's??

This is 8th grade? I learned this in 7th grade

Step-by-step explanation:

1. Slope= 3/4x (MAKE SURE TO PUT THE X) Y intercept = +7 (MAKE SURE YOU PUT A + IF IT IS POSITIVE AND - IF NEGATIVE

2. Slope = 5x  Y intercept = 8 (I think this was a trick question?)

3. Slope = -2x Y intercept = 0 (So just keep it empty or say 0 if your teacher is like that)

4. Slope = x Y intercept = +12

I can't see the full question so sadly I can't help with the otherones

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
