I need help i dont know how to do this

Step-by-step explanation:

Given the two points, you'll have to solve for the slope. Once you have the slope, then you could easily solve for the y-intercept and have the equation of the line.

First, given the following points, (6, 8) and (2, -2):

Let (x1, y1) = (2, -2)

(x2, y2) = (6, 8)

Substitute these values into the slope formula:

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

m = [8 - (-2)] / (6 - 2)

m = (8 + 2) / 4

m = 10/4

m = 5/2 (This is the slope of the line).

Next, we need to determine the y-intercept.  The y-intercept is the y-coordinate of the point (0, b) where the graph crosses the y-axis.  Using the slope, m = 5/2, and one of the given points, (6, 8), substitute these values into the slope-intercept form to solve for the y-intercept, b:

y = mx + b

8 = 15 + b

Subtract 15 from both sides to isolate b:

8 - 15 = 15 - 15 + b

-7 = b

Therefore, the y-intercept, b = -7.  And its coordinates: (0, -7).

Now that we have our slope, m = 5/2, and y-intercept, b = -7, we can establish the equation of the line in its slope-intercept form:

To graph the equation, start by plotting the y-intercept, (0, -7), then plot the next points using the slope, 5/2 (rise 5 units, run 2 units).

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
