What is the slope of the line shown in the graph? A 3/2 B) 2/3 C) -3/4 D) -2/3

garik1379 [7]

Answer:

Step-by-step explanation:

y-intercept is (0, 3)

x-intercept is (4.5, 0)

formula to find the slope from two points is

$slope = m = \frac{y2 - y1}{x2 - x1} = \frac{y1 - y2}{x1 - x2} \\$

then the slope of the line that crosses (0, 3) & (4.5, 0) is

$m = \frac{3 - 0}{0 - 4.5} = \frac{3}{ - 4.5} = - \frac{3}{ \frac{9}{2} } = - \frac{2}{3}$
