Answer: A: 3/2
Step-by-step explanation:
When we have a line that passes through the points (x1, y1) and (x2, y2), the slope of this line is:
s = (y2 - y1)/(x2 - x1)
In this graph we can see that the line passes through the points:
(0, - 3) and (2, 0)
Then the slope is:
s = (0 - (-3))/(2 -0) = 3/2
Then the correct option is A.
The gradient of the line shown above is A: [tex]\frac{3}{2}[/tex]
Slope of the line that passes through two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is :
slope [tex]=\frac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Now, from the given graph we can see that the line passes through the points:
(0, - 3) and (2, 0)
The slope is:
[tex]s = \frac{(0 - (-3))}{(2 -0)} \\=\frac{3}{2}[/tex]
Therefore the correct option is A.
