Question

Let p1= (-2,7) and (5,-12). 
a. Find the slope between p1 and p2. 
b. Find an equation of the line that goes through the point p1 and p2.
c. What is the x-intercept? 
d. What is the y-intercept?

anonymous · Answer

a. Find the slope between p1 and p2. 
slope = y2-y1/(x2-x1)

b. Find an equation of the line that goes through the point p1 and p2.
(y-y1) = slope* (x-x1)

c. What is the x-intercept? 
Put y = 0 to find x intercept 

d. What is the y-intercept? 
y = mx + b  ---- b is the y intercept
