I will medal and fan. This is more of a personal question so I can understand this better. So I am working on linear equations and graphing them. Can anyone please list some examples of something that I can substitute y=mx+b with. Please also give an explanation. Thanks so much🙂

Hmm not sure what you mean?

If I give you a point on a line and the slope of the line, could you tell me the equation of the line?

Similarly...If I give you the equation of a line, would you be able to tell me if a certain point is on that line?

And if I gave you the 'x' and 'y' intercepts of a line, would you be able to tell me the slope of that line and then the equation of the line?

Can you give me an equation and explain how to get the y intercept and slope?

An easy one: $$-20x+5y=10$$ First get the x variable on the left side of the equation. To do that add 20x to both sides. $$-20x+20x+5y=20x+10$$$$5y=20x+10$$Now you need to get the y by itself. To do that we divide by 5. $$\frac{ 5y }{ 5 }=\frac{ 20x }{ 5 } + \frac{ 10 }{ 5 }$$$$y=4x+2$$ So, the slope is 4 and the y-intercept is 2 I hope this helps and I also hope this is what you were looking for. =)
