ANSWER:
The 1st one: -3x + y = 5
ABOUT STANDARD FORM:
- Ax + By = C
- A & B & C are integers
- A & B are both non - zero
- This form is good to use when wanting to find the x & y intercepts of a line
y - 2 = 3(x + 1) --- IN POINT SLOPE FORM
y - 2 = 3x + 3
+ 2 + 2
y = 3x + 5 --- IN SLOPE INTERCEPT FORM
-3x -3x
-3x + y = 5 --- STANDARD FORM
Hope this helps you!!! :)
Answer:
PT = 17
Step-by-step explanation:
Since T is the midpoint of PQ, then
PT = TQ , substitute values
4x + 5 = 8x - 7 ( subtract 4x from both sides )
5 = 4x - 7 ( add 7 to both sides )
12 = 4x ( divide both sides by 4 )
3 = x
Thus
PT = 4x + 5 = 4(3) + 5 = 12 + 5 = 17
