Question 88

What is the equation of the line if its slope is -2/5 and y-intercept is 6?

Solution

Slope, $$m = \frac{-2}{5}$$ and y-intercept, $$c = 6$$

Equation of line = $$y = mx + c$$

=> $$y = \frac{-2}{5} x + 6$$

=> $$y = \frac{-2x + 30}{5}$$

=> $$5y = -2x + 30$$

=> $$2x + 5y = 30$$

=> Ans - (B)
