The points ( - 6,4) and ( - 5,u) fall on a line with a slope of - 7. what is the value of u?

u = - 3

Step-by-step explanation:

Calculate the slope m using the gradient formula

m =

with (x₁, y₁ ) = (- 6, 4) and (x₂, y₂ ) = (- 5, u)

m = = = - 7, hence

u - 4 = - 7 ( add 4 to both sides )

u = - 3

(- 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 )
