When the line rises/increases from left to right, then it is a .........................

Is (-1,-1) a solution to [-4x - 3y = -7]

Austyn and TJ were buying toys and games for families in need. Austyn bought 2 toys and 3 games for $105. TJ bought 1 toy and 5 games for $140. How much was a toy? How much was a game?

Please note: Answer should be typed as (t,g) where t stands for cost of toy and g stands for cost of game. For example: if cost of toy was $2 and cost of game was $3, the answer should be written as (2,3). This was an example.

If a vertical line drawn anywhere through the graph crosses the graph twice, then it is a function.

State if {(4, 5), (3, -2), (2, -9), (1, -16)} is a function or not

Find the output, or functional value for f(2) using f(x) = 3(x^2) - x
