In which m is the slope and b is the y-intercept(value of x when y = 0).
In this question:
Slope 4, which means that
.
So

Contains point (1,-8).

. We replace this into the equation to find b. So



So

Answer:
x=7

Answer:
9x+4<m
Step-by-step explanation:
<span>1/258 *(t^28)
= t^28 / 4^4
= t^28 4^-4
= (t^-7 * 4)^-4
= (4t^-7)^-4
