Weegy: The answer is "y =- 8x + 63"
User: Find the equation of a line with the given points. (Put your answers in the form y = mx + b.)
(1, -5)
(5, -1)
Weegy: y=x-6 is the equation of a line with the given points (1, -5) (5, -1)
User: Find the equation of a line with the given points. (Put your answers in the form y = mx + b.)
(6, 2)
(5, 5)
Weegy: The slope, m, will be the rise (difference in Y values) divided by the run (difference in X values).
(5-2)/(5-6) = 3/-1 = -3
So m = -3
So we have y = -3x + b
To find b, [ we plug in one of the points and solve.
2 = -3(6) + b
2 = -18 + b
20 = b
So our final equation for the line is:
y = -3x + 20 ]

(5, 4)
Weegy: you can follow these steps:
Given 2 points example.
Find the equation of the line thru the points (2,1) and (3,5)
- - - - - - - - - - -
This is a 2 step process. [ First find the slope of the line thru the points.
slope, m = diffy/diffx
m = (5-1)/(3-2)
m = 4
- - - - -
Now use y = mx + b with either point to find b, the y-intercept.
y = mx + b
5 = 4*3 + b
b = -7
- - - -
y = mx + b
y = 4x - 7 is the answer.
- - - - - - - - - - - -
Another approach using determinants:
|x y 1|
|2 1 1| = 0
|3 5 1|
- - - -
x(1-5) - y(2-3) + 1(10-3) = 0
-4x + y + 7 = 0
y = 4x - 7

The y-intercept of the line whose equation is 7x - 4y = 8 is -2.
When x = 0
7(0) - 4y = 8
-4y = 8
y = 8/-4 = -2 which is the value of y intercept.
