Question

For each line determine whether the slope is positive negative zero or underfined

Answer 1

Here, we want to check the type of slope each of the line has;

Basically, there are 4 slope types for linear equations

a) Positive slope

This type of slopes rise from right to left on the graph.

b) Negative slope

This type of slope falls from left to right. It does not rise

c) Zero slope

This is a type of slope that occurs when we have a constant y-value

Drawing a straight line through a point on the y-axis will give a zero slope

d) Undefined slope

This type of slope occur when we have a straight line through a point on the x-axis. If we draw a straight line passing through a point on the x-axis, then it is an undefined slope graph

With these definitions, we can solve for each individual line

line 1

This is a negative slope as it falls from the left to the right

line 2

This is a positive slope

It rises from left to right

line 3

This is an undefined slope as the line passes through a single point on the x-axis

line 4

This is a zero slope as the y-value does not change
