The graph of which of the following equations contains the points (2,3) and (3,2)

Crazy boy [7]

Answer:

$y = 5 - x$

Step-by-step explanation:

The graph of the equation that will contain the points (2, 3) and (3, 2) is the graph that has a slope value that is equivalent to the slope value of the line running through the two points.

Slope of the line running through (2, 3) and (3, 2):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 3}{3 - 2} = \frac{-1}{1} = -1$ .

Slope (m) = -1.

The equation, $y = 5 - x$ , is given in the slope-intercept form, which means it has a slope value of -1. I.e. the term "-x" is equivalent to -1x. So therefore, the graph of the equation that contains the points (2, 3) and (3, 2) is $y = 5 - x$ .

First add 1 to each side. It will leave you with an equation like this. 5x=3x -4

Next, subtract 3x from each side. It will leave you with an equation like this. 2x= -4

Lastly, divide each side by 2 so we can get x by itself.
