Question

Find the equation of the line containing the given pair of points... (-7,-1) and (-3,-2)

Answer 1

y = mx + b is line with m being slope and b is y-intercept.

Slope of two points is delta of y / delta of x. So, here slope m = -1/10.

y = -x/10 + b.

Plugging in point -3,-2 into that equation, you get value of b.

-2 = 3/10 + b
=> b = -23/10

So, equation is:
y = -x/10 - 23/10
