Answer:

A line that rises from left to right has positive slope.

Step-by-step explanation:

A horizontal line just goes from left to right but not up or down so y does not change at all. Change in y/change in x makes slope. Since y does not change, it has 0 slope which isn’t no slope.

A vertical line moves up and down but not left to right so there is no change in x. You cannot divide by 0 if you follow the equation y/0. So slope is undefined.

A line that rises from left to right goes in a diagonal direction is like a 2d hill. It is positive because change in y would be positive and change in x would be also positive. Positive/positive is positive making the slope positive.

A line that falls from right to left literally gives the same line so that means it is also positive slope, not negative.

Answer:

5x^2 + 20x = 5x(x + 4)

Step-by-step explanation:

Here, we want to factorize;

5x^2 + 20x

To do this, we start by writing the common factors

The common actor that we can see which is in the form of the gcf of both is 5x

Thus, the factorization will be;
