Find an equation of the line containing the give pair of points.
(-2, -1), and (-7,-4)
The equation of the line in slope-intercept from is y= what
The slope is
m = (y2-y1)/(x2-x1)
= [-4 -(-1]/[-7-(-2)]
= -3/-5 = 3/5
The equation will be of the form
y = (3/5) x + b
Use the coordinates of either point to solve for b
-1 = (-2)(3/5) + b = -6/5 + b
b = 1/5
Give the equation that is parellel to the following lines and passing through the given points:
(Y-6) = 4(X=3) (-2,7)
