y + 4 = 2(x + 3)
the equation of a line in ' point-slope form ' is
y - b = m(x - a )
where m is the slope and (a, b) a point on the line
here m = 2 and (a, b) = ( - 3, - 4)
y + 4 = 2( x + 3 ) ← in point-slope form
There are two answers for this question:
(-6,10)
(-6,-10)
because it doesn't say which direction the units go, it could be either of them, therefore type both answers in the box.

Answer:
The true statement is: In step 3 she needed to subtract c rather than divide.
Step-by-step explanation:
Lets solve our equation step by step.
Step 1. Since 3 is the denominator of the right hand side, we need to multiply both sides of the equation by 3:
Now we can cancel the 3 in the numerator and the 3 in the denominator to get
As you can see, the first statement is false
Step 2. Since we want to isolate the variable , we need to subtract b from both sides of the equation:
The second statement is also false
Step 3. The last thing we to do to isolate (and solve for it) is subtract c from both sides of the equation:
Therefore, the third statement is true: In step 3 she needed to subtract c rather than divide.
