<h3>Answer: C) 2</h3>
Explanation:
Recall that the general point-slope form is where m is the slope and
is the point the line goes through. We see that the 2 and the m match up, so m = 2 is the slope.
Side note: We can rewrite that given equation into y - (-5) = 2(x - (-1)) to see that the line goes through the point (-1, -5)
Answer:
Step-by-step explanation:
<u>Equation Solving</u>
We are given the equation:
i)
To make y as a subject, we need to isolate y, that is, leaving it alone in the left side of the equation, and an expression with no y's to the right side.
We have to make it in steps like follows.
Cube both sides:
Simplify the radical with the cube:
Multiply by 2y+9
Simplify:
Operate the parentheses:
Subtract 3y and :
Factor y out of the left side:
Divide by :
ii) To find y when x=2, substitute:
