Answer:
a. m = 2; y intercept = (0, 4); y = 2 x + 4
Step-by-step explanation:
The slope can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
m = (18 -4)/(7 -0) = 14/7
m = 2
The y-intercept is the first given point: (0, 4).
The equation for the line in slope-intercept form is
y = mx + b
Here, we have m=2 and b=4, so the equation is ...
y = 2x +4

Answer: Quadratic; 6x^2, x, -12
Detailed Explanation:
The highest power of the function (degree) is 2. Therefore it is a quadratic function. The quadratic term is 6x^2 since its power is 2, the linear term is x since its power is 1 and the constant term is -12.
Assuming this is the same test I just took, the answer would be 19.
2x + 1.5 y = 985
y = students
x = adults
x + y = 578
*-2 * -2
-2x - 2y = -1156
2x + 1.5y = 958
-2x - 2y = -1156 (add these together)
-0.5 y = -198
*-2 *-2
y = 396
x + 396 = 578
x = 182
396 students
182 adults
