Answer:
y =
x + 1
Step-by-step explanation:
The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope using the points (3, 3) and (0, 1).
Slope = 
=
Thus, the slope of the line is
.
Based on the graph, the y-intercept is 1.
Thus, the equation of the line is: y =
x + 1.
For this case we have a relationship of the form:

There are 70 children on the field trip
Therefore, we must replace the value of c = 70 in the equation.
We have then:

Clearing t, we have:

Answer:
(-5,-28)
Step-by-step explanation:
Given

Required
Find the coordinates of the vertex
Given that the function is a quadratic function;
The general form of a quadratic function is

By comparison;

To calculate the coordinates of the vertex;
we start by calculating the x-coordinate;

Substitute 10 for b and 1 for a



Substitute
in the given function;




<em>Hence, the coordinates of the vertex is (-5,-28)</em>
