Which is true for y=mx+b to have a negative x-intercept. a. the signs of the values of m and b are the same. b. the value of m is positive while the value of b is negative. c. the value of m is negative while the value of b is positive. d. the signs of the values of m and b do not affect the sign of the x-intercept.

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
