Answer:
x + y = 9
Step-by-step explanation:
Line is passing through the points (9, 0) and (0, 9)
-> y - intercept (b) = 9
& slope (m) = (9 - 0)/(0 - 9) = 9/(-9) = -1
Equation of line in slope-intercept form is given as:
y = mx + b
Plugging in the values of m and b in the above equation, we find:
y = (-1)x + 9
-> y = -x + 9
-> x + y = 9
This is the required equation of the line
[Note: there are several other points through which line is passing and those points can also be selected for finding the required equation]
