Answer: (0,-3)
Explanation:
Use the point slope form of a line: y = mx = b, where m is the slope and b is the y-intercept
First solve for m:
m = (Y2-Y1)/(X2-X1)
m = (1-0)/(4-3)
m = 1/1 = 1
Using the slope above, plug either point into the equation and solve for b. I used (3,0) but (4,1) would give the same result:
y = mx +b
0 = 1(3) + b
0 = 3 +b
-3 = b
SOLUTION: y-intercept is (0,-3)
