In this week I learned how to work with slope and graph. I learned when we have Y=3x +4,

The 3x is actually 3/1x. The Nominator is the amount of the units you go up and the denominator is the amount of the units you go right. The 4 is the Y-intercept which means it’s the number you start with. So when you have Y=3/1x + 4,  the first point is 4 on the Y axis, (0,4). then you go 3 units up and 1 unit right. that’s the second point. you keep doing that until you have enough points to draw the line.
