Complete the equation describing how
deff fn [24]

Answer:

y= -4x-6 is the required equation.

Step-by-step explanation:

Lets take (0,-6) and (1,-10)

now

slope = (y2-y1)/(x2-x1)

= ((-10+6)/(1-0)

= -4/1

so, m = -4

again

y=mx+c

or, -10=-4×1+c

or, -10 = -4+c

so, c = -6

now

y=mx+c

or, y = -4x-6
