have you seen the slop intercept form : y=mx+b?

alright so first you want y by itself correct? what can you do to get y by itself

you have 4y=123x
3 would be your slope and 12 is your y intercept?

not exactly , the equation says y=mx+b, not 4y=mx+b. so you need one more step to get y's constant to be one

now you should have it in y=mx+b where m = slope and b is your y intercept

12/4=3
3/4 = 3/4
