D=6

Find the y -intercept and the slope of the line.
daser333 [38]

Answer:

The slope is 5/2 and the y intercept is -1

Step-by-step explanation:

To find the slope and the y intercept, we will write the equation in slope intercept form, y =mx+b where m is the slope and b is the y intercept

5x -2y =2

Add 2y to each side

5x-2y+2y =2 +2y

5x = 2+2y

Subtract 2 from each side

5x-2 = 2y+2-2

5x-2 =2y

Divide each side by 2

5x/2 -2/2 = 2y/2

5/2x -1 = y

y = 5/2x -1

The slope is 5/2 and the y intercept is -1
