The y-intercept is whatever number (with no variable) is added onto the end of the equation y=mx+b. In this case b is the y-intercept. In y=15x the y-intercept is 0 because there is no number without a variable on the end.
First, make sure you understand what the x and y intercepts mean.When the line intersects or hits the y axis, x must be zero. Just look at the graph to see that.So if y=4x-14 and we want the y...
This is the equation of a straight line, and the form it's in is what they call the "standard form", where the slope and intercept of the line are as plain as my nose. The standard form is: Y = (this...
