Answer:
for the line to have a constant slope, the difference of every y- ordinate with the last ordinate has to be equal
to check this, we will use the following formula
y4 - y3 = y2 - y1
if both the LHS and the RHS are equal, the slope is constant and is irregular otherwise
5 - 8 = 7 - 3
-3 = 4
LHS ≠ RHS
Since LHS is not equal to RHS, the slope is NOT constant and hence keeps increasing or decreasing irregularly
Therefore, option 4 (Not a line) is correct

Assume ladder length is 14 ft and that the top end of the ladder is 5 feet above the ground.
Find the distance the bottom of the ladder is from the base of the wall.
Picture a right triangle with hypotenuse 14 feet and that the side opposite the angle is h. Then sin theta = h / 14, or theta = arcsin 5/14. theta is
0.365 radian. Then the dist. of the bot. of the lad. from the base of the wall is
14cos theta = 14cos 0.365 rad = 13.08 feet. This does not seem reasonable; the ladder would fall if it were already that close to the ground.
Ensure that y ou have copied this problem accurately from the original.
Answer:
The money Alex has left over at the end of the week is ( x - $15).
Step-by-step explanation:
The total lunch allowance of a week = $x
The money spent on lunch every weekday = $3
Number of weekdays in a week = 5 days
Now, the total money spend in 5 weekdays
= 5 x ( Money spend in 1 weekday) = 5 ( $3) = $15
So, in a week she spends $15 in a week.
Total amount Left = Total Money - Money Spent = x - $15
Hence, the money Alex has left over at the end of the week is ( x - $15).
