Answer:
Step-by-step explanation:
The equation of the line in slope-intercept form is:
y=mx+b
Where m the slope of the line and b the y-intercept.
When two points are given, it's convenient to calculate the slope first.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
The points are (3,5) and (-2,1):
The equation is now:
To calculate b, we use any of the given points and solve for b. Use (3,5):

Answer:
D) {1, 2, 3}
Step-by-step explanation:
Simply solve for m given our equation:
<em>11 = 3.50 + 2.50m</em>
Start by subtracting 3.50 on both sides:
<em>7.5 = 2.50m</em>
Next, divide by 2.50 on both sides to obtain our value for m:
<em>3 = m</em>
Now since we're looking for a complete set of values, we have to consider all values that are 3 and below for m. This makes D) our answer
