Question

For the equation, y = -4X - 5, tell whether it's graph passes through the first quadrant. Explain how you know

Answer 1

it does not pass through quadrant I.

Both the slope and Y value are negative.

Meaning this equation goes up to the left and down right.

(you can use a graphing calculator (if you have one.) and plug this equation into the GRAPH.) It will show you the line.

Answer 2

It doesn't passes because:

1) It has a negative gradient
2) It has a y-intercept of -5
