7 + 12 + 17 + 22 + 27 = ( 7 + 27 ) + ( 12 + 22 ) + ( 34 / 2 ) = ( 34 / 1 ) + ( 34 / 1 ) + ( 34 / 2 ) = ( 68 / 2 ) + ( 68 / 2 ) + ( 34 / 2 ) = 170 / 2 = 85 .

Find the slope and the y-intercept of the following graph

spin [16.1K]

Answer:

The slope of the graph is 5, and the y-intercept is (0, -3).

Step-by-step explanation:

Let's start by finding the y-intercept.

The y-intercept is the point where the line intercepts the y-axis.

Looking at the graph, we can determine that the y-intercept is (0, -3).

The slope of a graph can be found using two points on the line.

Let's use (0, -3) and (1, 2):

$Slope=\frac{Rise}{Run}=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-3)}{1-0}=\frac{5}{1}=5$

Therefore the slope of the graph is 5, and the y-intercept is (0, -3).
