Question 939880: Problem
For the points ( [a] , [d] ) and (1, [c] ), find
a) the distance between the points,
b) and the equation of the line passing through them.
Round all numbers to 1 decimal place and write your answer in slope-intercept form (y = mx + b).

a) Use the distance formula,
D%5E2=%28c-d%29%5E2%2B%281-a%29%5E2
D=sqrt%28%28c-d%29%5E2%2B%281-a%29%5E2%29
b) First find the slope.
m=%28c-d%29%2F%281-a%29
Then use the point slope form,
y-c=%28%28c-d%29%2F%281-a%29%29%28x-1%29
y-c=%28%28c-d%29%2F%281-a%29%29x-%28c-d%29%2F%281-a%29
y=%28%28c-d%29%2F%281-a%29%29x%2Bc-%28c-d%29%2F%281-a%29%29
