Find the equation of the line containing the following points (7,-11)(3,5).
Assign the given values as follows
x1=7, y1=-11
x2=3, y2=5
:
Use slope formula: m =
so we have
m = = = = -4 is the slope
:
Use the point/slope formula y - y1 = m(x - x1)
y - (-11) = -4(x - 7)
y + 11 = -4x + 28
y = -4x + 28 - 11
y = -4x + 17, is the slope/intercept equation
