Find the equation of the straight line passing through the points (2,-4) and (1,0)

4x + y = 4

Step-by-step explanation:

Firstly calculate your gradient

;Gradient = (-4 - 0)/(2 - 1)

;Gradient = -4

Then use the formula;

y - y(y - coordinate of any of the two points given) = Gradient(x - x(x - coordinate of any of the two points given but must be from the same point as that you used in your y - coordinate))

; y - (-4) = -4(x - 2)

; y + 4 = -4x + 8

;Equation of the line..,

4x + y = 4
