state the slope and y intercept for the graph of y =-4x
It is absolutely essential that you know:
if y = mx + b is the equation of a straight line,
the slope = m
the y-intercept is b
How does your equation y = -4x match up with y = mx + b ?
if y = mx + b is the equation of a straight line,
the slope = m
the y-intercept is b
How does your equation y = -4x match up with y = mx + b ?
