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)

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

The slope of the (3, 8) and (-2, 5) is ; m = y1-y0 /x1-x0 = 5 - 8 / -2 -3 = -3 /-5 = 3/5 = 0.6

Input the equation of the given line in standard form.The line with m = -3/4 and b = -2. **Weegy:** First, create a slope-intercept equation. y= (-1/2)x + b
To find b, plug in (-2, -3)
-3 = (-1/2)(-2) + b
-3 = 1 + b
-4 = b
y= (-1/2)x - 4
Now convert to standard form, which means getting both x and y on the same side. [ So we can add (1/2)x to each side
(1/2)x + y = -4
multiply by two to get rid of the fraction
x + 2y = -8 ] (More)
