Write a system of equations that has 2 lines that intersect at (-3,7) and have (-3,7) as a solution and show me how to solve it.
:
We can choose the slopes then use the point slope formula; y-y1 = m(x-x1)
slope of the 1st line m=3
y - 7 = 3(x - (-3))
y - 7 = 3(x + 3)
y - 7 = 3x + 9
y = 3x + 9 + 7
y = 3x + 16, 1st line equation
:
slope of the 2nd line m=-4
y - 7 = -4(x - (-3))
y - 7 = -4(x + 3)
y - 7 = -4x - 12
y = -4x - 12 + 7
y = -4x - 5, 2nd line equation
:
will look like this
