Graph the equation using slope and the y-intercept
y=4x-1

y intercept:

slope: -1

Step-by-step explanation:

1) We know that y intercepts are when x equals zero! Since we have an equation, we can plug in the value 0 for x to find out the y intercept.

If we do this:

y= 4 x 0 -1

y=-1

This means that the y intercept is: (0,-1)

Y intercepts will be on the y axis. So, graph (0,-1) on your chart.

2) Next, we know that slope is change in y over change in x. So if the slope is -1, we can say that if we move down 1, we move to the right 1.

If we apply the slope to our y intercept you will get a line!

3) If you are still confused, here are some points that belong to this line. If you check, you will see that the slope is -1 ( down 1, to the right 1)!

a) (1, 3) ---> all I did to discover this point is plug in 3 for y in the equation.

b) (2, 7) ---> I plugged in 7 for y

Good luck! Hope this helped.
