What is the slope-intercept form of any linear equation?
What does “m” stand for in the slope-intercept form of a linear equation?
What does “b” stand for in the slope-intercept form of a linear equation?
y = 2 x + 4 Where is the y-intercept?
y = 2 x + 4 What is the slope?
y = 6 x + 23 What is the slope?

3.7 Equations of Lines in the Coordinate Plane The slope m of a line is the ratio `of the vertical change (rise) to the horizontal change (run) between.
X and Y intercepts. X-intercept: The point where a line crosses the x-axis. The coordinates are ( x, 0) where x is any number on the x-axis Y-intercept:
