Spent 50 points on this question
in the table, x represents minutes, and y represents the altitude of an airplane.
table
x y
15 22,500
20 20,000
25 17,500
30 15,000
which statement is correct about the slope of the linear function that the table represents?
a. the slope is positive because as the minutes decrease, the altitude increases.
b. the slope is positive because as the minutes increase, the altitude increases.
c. the slope is negative because as the minutes decrease, the altitude decreases.
d. the slope is negative because as the minutes increase, the altitude decreases.

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
