Question

Which form of a linear equation is best used when given the steepness of the line along with the point where the line crosses the y-axis?

Answer 1

slope-intercept form.
Slope intercept form is y = mx + b, m is slope and b is y-intercept.

the "steepness" is m
and the "point where the line crosses the y-axis" is the y-intercept, which is "b" value.
