The required equation of the line passing through (9, 2) and (3, 5) is y = -0.5x - 6.5
The standard equation of a straight line is expressed as u = mx + b
m is the slope of the line
b is the y-intercept
Given the coordinate points (9, 2) and (3, 5)
Get the slope of the line
Slope = 5-2/3-9
Slope = -3/6
Slopee =-1/2
Get the y-intercept
Recall that y = mx + b
2 = -1/2(9) +b
2 = -4.5 + b
b = 6.5
Hence the required equation of the line passing through (9, 2) and (3, 5) is y = -0.5x - 6.5
