Answer:
Slope m = 1/-2
Step-by-step explanation:
Given the formula for slope of a line to be
m = y - y_1 / x - x_1
Only if a point is given
But in this case, we are given two points
( 1 ,4 ) and ( -1 , 5)
x_1 = 1
y_1 = 4
x_2 = -1
y_2 = 5
Inserting the values given into the formula
m = y_2 - y_1 / x_2 - x_1
m = 5 - 4 / -1 - 1
= 5 - 4= 1
= -1 - 1 = -2
m = 1/ -2
Therefore, the slope of the line is 1 /-2

The function has a domain of all real numbers . True
<em>The cube root of real number is also real. The negative sign is outside he radical so it cannot result to an imaginary number.</em>
The function is a reflection of y =³√x . True
The function is always increasing. False
<em>When getting the cube root of a number the result is alway smaller. So the domain of the function should be decreasing not increasing.</em>
The function has a range of {y|– < y < } . False
The function passes through the point (3, –27) . False
<em>When this values are substituted it the function they don't satisfy it. </em>
4 units, because a translation is a rigid motion, meaning it preserves segment length.
3(b+6) = 3*b + 3*6 = 3b + 18
