Question

For the equation, y= -x | 4, tell whether its graph passes through the first quadrant. Explain how you know. a. Yes; for x > 0 some y-values are positive. b. Yes; for x < 0 some y-values are positive. c. No; for x < 0 the y-values are negative. d. No; for x > 0 the y-values are negative.

Answer 1

@iambatman @bloopman help plz

Answer 2

@masumanwar help plz is it A?

Answer 3

for a function to be in first quadrant all the coordinate values are to be positive

Answer 4

If the graph passes through the first quadrant, then there are at least some positive x-values that have positive y-values associated with them. ..

Answer 5

So, if it's in the first quadrant, y > 0 and -4+x > 0. Let's solve that inequality:
-4+x > 0, or
x > 4
We need x to be positive, and we see that . Therefore the line does pass through the first quadrant.
