Select answer

number is what you get when you multiply a positive number times a negative number

​y = mx + b

​Equation is known as slope intercept form

Will result in a straight line when drawn on a graph

​y = mx + b

​Equation is known as slope intercept form

Will result in a straight line when drawn on a graph


m = slope (how the line Moves)

​y = mx + b

​Equation is known as slope intercept form

Will result in a straight line when drawn on a graph


m = slope (how the line Moves)

b = y-intercept (where to Begin)
