Hello!
Slope - Intercept Form:
- m = slope
- b = y-intercept
The slope of the line is the rate of change, or how the graph changes in y as it changes in x.
Slope can be calculated by the formula:
We need two points on the line to get the x and y-values. I'm going to choose points (0,5) and (4,-3).
Calculate Slope
The slope is -2.
<h3>Y-intercept</h3>The y-intercept of the line is where the graph touches the y-axis (x = 0). It can be found by looking at the intersection of the graph and the axis.
The intersection happens at point (0,5), so the y-intercept is 5.
<h3>Equation</h3>We found m, the slope, to be -2 and b, the y-intercept, to be 5. We can just plug it into the equation format.

Answer:
There are 700 books in Library Collections.
Step-by-step explanation:
Given:
Number of historical books = 70
The equation used to find the totals number of books in library collection.
where b⇒ Total number of books in library collections.
We need to find the Total number of books in library collections.
Solution:
Now by solving the above equation we get;
First we will multiply both side by 10 we get;
Hence there are 700 books in Library Collections.
Answer:
Step-by-step explanation:
Let x be the smaller number.
The next even number will be (x + 2).
Subtract 2 from both sides:
Divide both sides by 2:
The smaller number is 32.
Larger number
