Can someone explain to me how to work with the slope-intercept formula: y=mx+b ?

Question

campbell_st · Answer

so what is it about the slope intercept equation that causes you a problem

I need help on understanding the different variables that the formula has. @campbell_st

ok... 

so x is the independent and y is the dependent variables.... 

m is the slope of the line   

b is where the line cuts the y-axis... called the y-intercept

so 

y = 3x + 5

the slope is 3 and the y-intercept is 5  or (0, 5)


y = 10 - 2x     the slope m = -2 and y-intercept is 10


y = 12     slope = 0      y-intercept is 12

hope it helps

That means for any (x,y) pair, y=mx+b the equality holds.
