The graph shows a line that represents the relationship between variables x and y.
Where the line croses the y-axis, the point is called "y-intercept" and it is equal to (0,3)
Where the line croses the x-axis, the point is called "x-intercept" and is equal to (-10,0)
To calculate the slope you have to use two griven points, for example the y-intercept (0,3) and the point (3,4). The formula to calculate the slope is:
[tex]m=\frac{y_1-y_2}{x_1-x_2}=\frac{4-3}{3-0}=\frac{1}{3}[/tex]
The slope of the line is equal to 1/3
The correct choice is: 1. The y-intercept is 3, and the slope is 1/3
