Question

Work out the equation of the line which has a gradient of a 1\2 and passed through the point (4,-2)

Answer 1

Step-by-step explanation:

Given : m = 1/2 Point P(4,-2)

Let the required line be y = mx + c ... equation (1)

putting the given data in above line we have :

-2 = (1/2)*4 + c

or c = -4

putting value of c and m in equation 1

y = (1/2)x + (-4)

or y = x/2 - 4
