Find the slope of 2, 1 and -1, -1
The slope of the line passing through points (2, 1) and (-1, -1) is: 2/3. m = (y2 - y1)/(x2 - x1) m = (-1 - 1)/(-1 - 2) m = -2/-3 m = 2/3

The slope of the line passing through points (2, 1) and (-1, -1) is: 2/3.

m = (y2 - y1)/(x2 - x1)

m = (-1 - 1)/(-1 - 2)

m = -2/-3

m = 2/3

The line through (0, -3) and (3, 0) in standard form is x - y = 3

3x - 2y = 6
-2y = -3x + 6
y = 3/2x - 3 which is the slope intercept form
so slope m = 3/2, y intercept = -3

Solve the given equation for the slope and y-intercept. 2x + 5y + 1 = 0
Question
Updated 7/26/2014 9:21:50 AM
2x + 5y + 1 = 0
5y = -2x - 1
y = -2/5x - 1/5 which is the slope intercept form of the line equation.

Find the common solution. 7x + 2y = 4 y = x + 1
Weegy: 2x +7y = 5 Just move the second one to the first one and then the answer is that in above. (More)
Question
Updated 5/24/2014 9:45:40 AM
7x + 2y = 4
y = x + 1
using the second equation to institute y in the first one:
7x + 2(x + 1) = 4
7x + 2x + 2 = 4
9x = 4 - 2
x = 2/9
y = 2/9 + 1 = 2/9 + 9/9 = 11/9
The solution for the system 7x + 2y = 4 y = x + 1 is (2/9, 11/9)
