Question

Indicate in standard form the equation of the line passing through the given points.

E(-2, 2), F(5, 1)

Answer 1

First find the slope of the line. y2-y1/x2-x1
Slope = m = 1-2/2--5 = -1/7

Next: substitute values into the equation y=mx+b

2 = (-1/7)(-2)+b
2= 2/7 + b
12/7 = b

So you've got: y = -1/7x + 12/7
Standard form is Ax + By = C

1/7x+y = 12/7
7(1/7x+y = 12/7) = x+7y=12

Answer 2

can you explain the ax+by=c
