Explanation
when you know the slope and a passing point of the line, you can find the equation of the line by replacing in the slope-point equation ,it is given by:
then
Step 1
a)Let
now,replace and solve for y
therefore, the answer is
I hope this helps you
Option B:
The solution to the given inequality is x ≤ 8.
Solution:
Step 1: Given expression is the inequality.
9x ≤ 72
Step 2: To find the solution to the inequality:
9x ≤ 72
Step 3: Divide by 9 on both sides of the inequality.
Step 4: The solution is x ≤ 8
The solution to the given inequality is x ≤ 8.
Hence Option B is the correct answer.
