Find the slope and the \( y \)-intercept of the line. \[ 7 x+y=1 \] Write your answers in simplest form.

Write the function whose graph is the graph of \( y=(x+4)^{2} \), but is reflected about the \( x \)-axis. \( y=\square \) (Simplify your answer.)

\( 19 j-86 \geq 5 \) or \( 27 j-82 \leq 18 \)

3. \( 3 x(4 x-5) \)

4. Jug A contains 5 times as much water as Jug B. After some water is poured from Jug A to Jug B, there are 1860 ml of water in each jug. How much water is poured from Jug A to Jug B?

QUESTION 3 3.1 Given the number pattern \( 2 ; y ; 8 ; \ldots \) Determine the value of \( y \) if: 3.1.1 The number pattern is linear. 3.1.2 The number pattern is quadratic and \( T_{4}=2+5 y \). 3.2 In a linear number pattern, the \( 19^{\text {th }} \) term is 40 and the \( 7^{\text {th }} \) term is 16 . Thus, determine the first two terms. 3.3 The general term of a quadratic number pattern is \( T_{n}=n^{2}+2 n-15 \). Determine which term has a value of 20 .
