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.

Answer:
a)
b)
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.
Point slope:
a) in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is .
We will substitute and .
This simplifies to:
b) The equation y=3x+4 follows y=mx+b. For the perpendicular line, . We will need to change it into its negative reciprocal which is .
We will substitute and .
