u need to know this in 8th grade

Wording is important here. The y-intercept is where the line crosses the y-axis (touches the y-axis). Great question. Hope this helps. <|:)

I'm not completely sure what you mean, but I'll try to explain as best as I can: You're not supposed to solve the equation for y=mx+b. For y=mx+b i...

There are many real-life examples of lines that would be in slope-intercept form. It moves from theory to practical in many fields of study as well...

Thou must think 2 dimensionally. Thou art solving for y, without an x. Furthermore, thou havest infinite x values so thy graph shall be a straight...

The line goes on infinitely, but infinity slopes kind of exist. If there is a line going straight up and down, the slope will be undefined, or infi...

Good question. To find the x-intercept we generally just use the same formula 'y=mx+b'. The reason that 'b' is the y-intercept is because at the 'y...
