Which statement about the slope of a line is true? A line with a negative slope increases as it is viewed from left to right. A line with a positive slope increases as it is viewed from left to right. A line with a positive slope decreases as it is viewed from left to right. I don't know.

The correct answer is the second option: A line with a positive slope increases as it is viewed from left to right.  

Step-by-step explanation:

To begin with, what it is known as the "slope" in these mathematics terms it refers, in simply words, to the inclination that the line has. Moreover, it describes the direction and the steepness of the line. There could be two types of slopes, a positive one and a negative one. The first one indicates that the line grows from the bottom to the top from left to right in the diagram or in the chart. And the other one, indicates that the line goes from the top to the bottom from the left to the right in the chart.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
