The percentage increase of the value of Tessa's stock is 21%.
<h3>Percentage increase</h3>
Using this formula
Percentage increase=Current stock worth-Old stock worth/Old stock worth
Where:
Current stock worth=$297.66
Old stock worth=$246.00
Let plug in the formula
Percentage increase=$297.66 - $246.00 / 246.00 × 100
Percentage increase=$51.66/ 246.00 × 100
Percentage increase=21%
Inconclusion the percentage increase of the value of Tessa's stock is 21%.

A linear function is when a variable y varies directly with a variable x. That is, when y increases, x also increases and the opposite is also true. THerefore, the correct answer from the choices listed above is the first option.

Answer:
(3, 50) and (14,303)
Step-by-step explanation:
Given the system of equations;
y=23x–19 ....1
x²–y= – 6x–23 ...2
Substitute 1 into 2;
x²–(23x-19)= – 6x–23
x²–23x+19= – 6x–23 .
x²-23x + 6x + 19 + 23 = 0
x² - 17x + 42 = 0
Factorize;
x² - 14x - 3x + 42 = 0
x(x-14)-3(x-14) = 0
(x-3)(x-14) = 0
x = 3 and 14
If x = 3
y = 23(3) - 19
y = 69-19
y = 50
If x = 14
y = 23(14) - 19
y = 322-19
y = 303
Hence the coordinate solutions are (3, 50) and (14,303)
