Answer: y = -1/5x + 10
Explanation:
1. Slope intercept-form formula
y = mx + b
Where m is the slope and b is the y-intercept.
2. Find the y-intercept
The y-intercept occurs when the x-value is equal to 0. When we look at the graph when the x equals 0, y equals 10. Therefore your y-intercept is 10.
3. Find the slope
In order to find the slope use the formula: (y2-y1) / (x2-x1)
Plug in the points that you would use:
(8 - 10) / (10 - 0) = -2 / 10 = -1/5
4. Substitute the values into the slope intercept equation
y = -1/5x + 10
