Question

Work out the equation of a line when the gradient is 1/2 and it passes through the point (4,-2)

Answer 1

Answer:

The equation of the line is

$y = \frac{1}{2} x - 4$

Step-by-step explanation:

Equation of a line is y = mx + c

where m is the gradient

c is the y intercept

Gradient = 1/2

Equation of the line using point ( 4 , -2) is

$y + 2 = \frac{1}{2} (x - 4) \\ y + 2 = \frac{1}{2} x - 2 \\ y = \frac{1}{2} x - 2 - 2 \\ y = \frac{1}{2} x - 4$

Hope this helps you
