Exercise 9.3
37. (i) Given, x + 7y = 0.
7y = -x
y = x + 0.
Comparing the above equation with y = mx + c we get, slope, m = - and c = 0, y-intercept
(ii) Given, 6x + 3y - 5 = 0
3y = -6x + 5
y = - x + = -2x +
Comparing the above equation with y = mx + c we get, slope, m = -2 and , y-intercept
(iii) Given, y = 0
y = 0xx + 0
Comparing the above equation with y = mx + c we get, Slope, m = 0 and c = 0, y-intercept.
