Answer:
the equation of the line = y + x -3 -3 = 0
Explanation:
Equation of the line is give n by the formula
y - y¹ = m
x - x¹
note: m is the gradient.
Point = (3, 3) and (-1, 7).
Gradient =m= y2 - y1 = 7 - 3 = 4 = -1
x2 - x1 -1 -3 -4
the equation of the line
y - y1 = m
x - x1
y - 3 = -1
x - 3
note: Perform cross multiplication also remember every whole number is over one.
=y - 3 = -1 (x - 3)
=y - 3 = - x + 3
y + x - 3 - 3 = 0.
