Best ResponseYou've already chosen the best response.0Well when we write out the equation of the line, we look for 2 things. The slope and the yintercept. The yintercept is what the y value will be when x is 0. Are you with me so far?

Best ResponseYou've already chosen the best response.0So we are going to write it out in the form \[\large y=mx+b\] with m as the slope and b as the yintercept. What do you think it would look like in this form?

Best ResponseYou've already chosen the best response.0Well m is the slope. So it HAS to be 4, right?

Best ResponseYou've already chosen the best response.0ok so slope is 4 but im still confused

Best ResponseYou've already chosen the best response.0Here, let's take out the b for a second. \[\large y=4x\] So what happens when you plug in 0 for x?

Best ResponseYou've already chosen the best response.0Yes, sorry for the delay. So if we have \[\large y=4x\] what will we get if we plug in 0 for x?

Best ResponseYou've already chosen the best response.0just x right because 4*0=0

Best ResponseYou've already chosen the best response.0Yes so \[\large y=4*0\\\large y=0\] So when x is 0, y is 1. That means our yintercept is 1. So now that we know that, how would we write the equation?

Best ResponseYou've already chosen the best response.0Yes, that would be it. Good job :)
