Perhaps you mean "slope-intercept" form. Solve for y and reduce the fractions.
.. -8x -6 = 2y . . . . . . . . add 2y-6
.. y = -4x -3 . . . . . . . . . divide by 2
Your line in slope-intercept form is
.. y = -4x -3
1. 4.374
2. 52.64
3. 840.5
Priscilla's age was 83,534 while Jack's age was 83,633.
Y2-y1/x2-x1= -47-(-7)/-19-(-9)= 4
