Answer:
Explanation:
The given points are:
- (0, 275)
- (1, 220)
- (2, 165)
- (3, 110)
- (4,55)
- (5, 0)
Since a <em>straight line joins</em> all the points, the equation that models the <em>relationship</em> is linear and you can find the slope-intercept equation which has the general form:
Where:
is the slope
is the y-intercept
<u>1. Find the slope</u>
You can use any two ordered pairs.
- m = rise/run = Δy/Δx = [220 - 275] /[1 - 0] = - 55
<u>2. Find the y-intercept</u>
The y-intercept is the value of y when x = 0; thus it is 275.
- b = 275
<u>3. Substitute in the slope-intercept equation</u>
That is the last option.
