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

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

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

m = -2/-3

m = 2/3

3x - 2y = 6

-2y = -3x + 6

y = 3/2x - 3 which is the slope intercept form

so slope m = 3/2, y intercept = -3

-2y = -3x + 6

y = 3/2x - 3 which is the slope intercept form

so slope m = 3/2, y intercept = -3

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)

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)

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)
