20. y intercept The y intercept is where the line crosses the y axis. y axis y intercept y intercept = 2 x axis
21. y intercept y intercepts can be positive or negative numbers y axis x axis y intercept= +1 y axis x axis y intercept= -2

23. Graphing Slope Intercept Form Step one: graph y intercept on y axis Step two: from that point use slope to graph second point Step three: connect the points You have now graphed a line using slope-intercept form.
27. Point slope form requirements You must have one point and the slope of the line in order to write in point-slope form. You then substitute the slope in for the letter m and the numbers from the point in there correct spot.
