Question 810236: What would be the intercepts of the line that contains pair of points:
" (-1,-4) and (6,10) " ?
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! points on line:
(-1, -4)
(6, 10)
---
use two-point form:
y - y1 = ( (y2 - y1)/(x2 - x1) )(x - x1)
---
y + 4 = ( (10 + 4)/(6 + 1) )(x + 1)
y + 4 = ( (14)/(7) )(x + 1)
y + 4 = 2(x + 1)
y + 4 = 2x + 2
y = 2x - 2
---
intercepts:
---
a is the x-intercept:
y = 2x - 2
0 = 2x - 2
2 = 2x
x = 1
a = (1, 0)
---
b is the y-intercept:
y = 2x - 2
y = 2(0) - 2
y = -2
b = (0, -2)
