Using the slope - intercept format, the equation which models the data represented by the graph is d(t) = -50t + 300
<u>According</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>general</u><u> </u><u>form</u><u> </u><u>of a</u><u> </u><u>linear</u><u> </u><u>regression</u><u> </u><u>equation</u><u> </u><u>:</u>
- y = bx + c
- <em>b</em><em> </em><em>=</em><em> </em><em>slope</em><em> </em><em>;</em><em> </em><em>c</em><em> </em><em>=</em><em> </em><em>intercept</em><em> </em>
Slope, b = (Δy ÷ Δx)
Slope = (200 - 50) ÷ (2 - 5)
Slope = 150 ÷ -3 = -50
Intercept is the point where the regression line crosses the y - axis.
From the graph, the intercept = 300
Hence, the regression equation is y = -50t + 300
