Question 629918
I would first compute the slope (m) as Δy/Δx = (y2 – y1) /(x2 – x1)


m = (7-6)/(2-4) = -1/2


The equation for a line is y = mx + b; where m is the slope and b is the y intercept.


So we know that the equation is y = -1/2*x + b; but we need to solve for b.


Select either data point and use it to solve for b by enetring the data into the equation. I will use the point (4,6).


6 = -1/2*4 + b


6 = -2 + b


b = 8


So the equation is y = -1/2*x + 8


Check by testing with both data points.
