What is the definition for the slope of a line???

What is the definition for the y-intercept???

Slope line- s a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line. Try this Adjust the line below by dragging an orange dot at point A or B. The slope of the line is continuously recalculated.

Y-intercept- to find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y.
