A linear equation is an equation that represents a line. A linear equation has a variable raised to the 1st power.
For example, Y = 2x, Y = x + 1, Y = 8x - 3 are examples of linear equations.
However, something like and seem to have a variable raised to the 1st power, but they're not linear.
7(x+3)
= 7x+ 7*3 (distributive property)
= 7x+ 21.
The final answer is 7x+21~
Answer: it’s a

Answer:
14 is a function, 15 is also a function
Step-by-step explanation:
You can use the vertical line test to see if a curve is a function. If the vertical line intersects the graph more tha one time, it not a fuction. If only one time, it is a function.
