Question

Input in standard form the equation of the given line that passes through (-1,-3) and (2, 1)

Answer 1

y=4/3x-5/3

Explanation:

We can use the slope formula, m=(y2-y1)/(x2-1), to find the slope.

1-(-3)/2-(-1)=4/3

We can subsitute now that we have the slope.

y=4/3x+b

-3=4/3(-1)+b

-3+4/3=b

b=-5/3

y=4/3x-5/3
