-2 + 3b = 5b - 2(2b + 3)  Distribute the -2 through the parentheses.
-2 + 3b = 5b - 4b - 6        Combine like terms
-2 + 3b = b - 6                 Bring all "b's" to one side of the equation
-2 + 3b - b = b - b - 6       Combine like terms
-2 + 2b = -6                      Bring the 2 to the right side of the equation
-2 + 2 + 2b = -6 + 2          Combine like terms
2b = -4                              Isolate b by dividing both sides by 2
b = -4/2 = -2

Answer b = -2

Write an equation that passes through a pair of points
Phoenix [80]

Answer:

C. y = -x + 2

Step-by-step explanation:

First, find the slope, m, of the line that passes through the two given points.

Slope = \frac{rise}{run} = \frac{-2}{2} = -\frac{1}{1} = -1

Next, determine the y-intercept, b.

The y-intercept is where the line intercepts the y-axis. The line intercepts the y-axis at y = 2. Therefore, b = 2.

Now, to get an equation of the line, substitute m = -1, and b = 2 in y = mx + b.

✅The equation would be:

y = -1x + 2

y = -x + 2
