SLOPE-INTERCEPT FORM• THE SLOPE-INTERCEPT FORM OF A LINE IS THE MOST COMMON FORM OF A
LINE• DESCRIBES A LINE AND ALL OF THE POINTS CONTAINING THAT LINE• ALLOWS YOU TO QUICKLY IDENTIFY THE SLOPE AND THE Y-INTERCEPT• SLOPE-INTERCEPT FORM:
WHICH OF THE FOLLOWING ARE WRITTEN IN SLOPE-INTERCEPT FORM?
WRITE AN EQUATION IN SLOPE-INTERCEPT FORM GIVEN TWO POINTS.•FIND THE EQUATION OF THE LINE THAT PASSES THROUGH (-1,4) AND
