1. Find the slope of the line through the pair of points.
(1/3,0) and (1/2,1/2)
Choices:
3
1/3
1/3
3
2. Write in standard form an equation of the line passing through the given point with the given slope.
Slope=8/7; (5,3)
Choices:
8/7x+y=61/7
8/7x1=61/7
8/7x+y=61/7
8/7x+y=61/7

You're more likely to get help if you post what you think are the answers.

slope = difference in y values/difference in x values
= (1/2  0)/(1/2 + 1/3)
= (1/2) / (1/6)
= (1/2)(6) = 3
2. y = (8/7) + b
sub in the given point
3 = (8/7)(5) + b
multiply by 7
21 = 40 + 7b
b = 61/7
y = (8/7)x  61/7 or
(8/7)x  y = 61/7
better form would be
8x  7y = 61
btw, none of your answers match with
(8/7)x  y = 61/7 which is the answer in the form of the other answers.
I would not consider any of the given answers to be in standard form
Most text books consider "standard" form to be in the form
ax + by = c, where a,b, and c are integers.

My first line of #2 should have been
2. y = (8/7)x + b
