Write an equation of the line below.

9514 1404 393

  y = x + 1

Step-by-step explanation:

Points (-8, -7) and (0, 1) are marked on the line. These can be used to find the slope of the line using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (1 -(-7))/(0 -(-8)) = 8/8 = 1

The y-intercept is the y-value where the line crosses the y-axis. That point is marked, and its y-value is 1.

Then the slope-intercept form of the equation for the line is ...

  y = mx + b . . . . . . line with slope m and y-intercept b

  y = 1x +1 . . . . . fill in the values for m and b

  y = x +1 . . . . . the coefficient of x is understood to be 1
