Use cymath it gives you the math answers but the answer is x=74
Yes, (3, 2) is a solution to y = 2x - 4. (:
If you show that the example is showing a false statement then you are disproving the example/problem.
Point slope equation for point (h,k) and slope m is given by
y-k=m(x-h)
compare given equation with formula
we get h=-7, k=3
so the required point is (-7,3)
