Referring the chart I attached, the slope is the ratio of rise to run
So we need to pick two points lying on the line to calculate the slope.
They would be (4,0) and (0,2)
[tex]slope= \frac{rise}{run} = \frac{\Delta y}{\Delta x}=
\frac{y_2-y_1}{x_2-x_1} = \frac{2-0}{0-4} = -\frac{2}{4} = -\frac{1}{2}
[/tex]
That is for the slope
The y-intercept is where the line touches\crosses\intersects the y-axis...
It is clear from the figure that the line crosses the y-axis at (0,2)
so the
y-intercept is [tex]y=2[/tex]
I hope that
helps!
If you still need help, just let me know!
