the graph highlights two other points on the trend line. use them to find another equation for the trend line shown for this scatterplot.\ny = 82x + 998\ny = 247.7x - 335\ny = 743x - 1647\ny = 998x + 82
Answer
Answer:
y = 82x + 998
Explanation:
Step1: Recall slope - formula
$m=\frac{y_2 - y_1}{x_2 - x_1}$, with $(x_1,y_1)=(2,1162)$ and $(x_2,y_2)=(11,1900)$.
Step2: Calculate the slope
$m=\frac{1900 - 1162}{11 - 2}=\frac{738}{9}=82$.
Step3: Use point - slope form
$y - y_1=m(x - x_1)$, substituting $m = 82$, $x_1 = 2$, $y_1=1162$ gives $y-1162 = 82(x - 2)$.
Step4: Simplify to slope - intercept form
$y-1162=82x-164$, then $y = 82x+998$.
