Answer:
The slope of the other line is -4/5
Step-by-step explanation:
In this question, we are asked to calculate the slope of a line which is perpendicular to the line ;
10x - 8y = -80
The first thing to do here is to write the equation in the standard form for a linear equation.
The standard form is y = mx + c where m refers to the slope and c refers to the y-intercept
Rewriting the equation we have;
8y-80 = 10x
8y = 10x + 80
Now divide the through by 8
We have;
y = 10x/8 + 10
Thus, comparing with y = mx + c , our m here is 10/8
Now for the two lines to be perpendicular, the product of their slope would be equals to -1
Let’s say the slopes are m1 and m2
mathematically m1m2 = -1
since m1 = 10/8
10m2/8 = -1
m2 = -8/10
m2 = -4/5
It is simplified as much as it can go.
It moves in a horizontal line. Its 'y value' does not change.

Answer:
see explanation
Step-by-step explanation:
By the rational root theorem, any rational roots of f(x) are expressible in the form
for integers p and q
with p a divisor of the constant term 6 and q a divisor of the leading coefficient 1.
The possibilities are ± 1, ± 2, ± 3, ± 6
Since the lead coefficient is 1 dividing by that number doesn't change a thing.
Thus the possible rational roots are
= - 6, - 3, - 2, -1, 1, 2, 3, 6
