Step-by-step explanation:

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. ... A parabola intersects its axis of symmetry at a point called the vertex of the parabola.

What is the slope of the line that passes through the points (2, 3) and (8, 6)? 2/7 2 3/5 1/2

baherus [9]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

THe slope of a straight line is given by the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Where

m is the slope

x_1 and y_1 are the first coordinate pair points [(2,3)]

x_2 and y_2 are the second coordinate pair point [(8,6)]

So, we know that:

x_1 = 2

x_2 = 8

y_1 = 3

y_2 = 6

Now we substitute and find the value of slope to be:

$m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{6-3}{8-2}\\m=\frac{3}{6}\\m=\frac{1}{2}$
