Answer:
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.
