Question

please someone answer number 1 and number 3!! it would be much appreciated if you could make it sound like and 8th graders work. thank you so much this is due tomorrow

Answer 1

Almost all linear equations are functions but not all straight lines are a graph of a function.A linear function with its y-intercept as zero passes through the origin.

step-by-step explanation:

1. Linear means a graph that makes a straight line where as a function represents all set of values in (x,y) system on a graph where a single x point has a corresponding y point value.

A function can be linear to form a straight line or a curve in the case of nonlinear functions.

The similarity is observed where both the straight line and the function assume the shape of a straight line. In this case, they are both linear. However, a function can be a curve and not a straight line, thus the difference.

3. The origin (0,0) and the y-intercept can be found in a table of values for a certain function and appear on the graph and the equation of a function. For example in the function y=4x, a table of value of x and y can be;

x           y

-1          -4

0           0

1            4

2           8

Here you notice when x=0, y=0, this tells you that the y-intercept is 0. From the slope intercept form of a graph, y=mx+c , c is the y-intercept, and for our case, y=4x, the value of c=0 to mean the function passes through the origin (0,0). This is observed in the table where x=0, y=0, on the attached graph where the line passes through the origin and in the equation y=4x where the value of c=0
