slope= changey/changex=(2-(-4))/(-1-(-10))
= 6/9
y= slope*x + Yintercept
using either pint (I will do the second)
2=6/9 * - 1 + Yintercept
Yintercept=8/3 which makes answer a the only possible answer.
check my work
A line passes through the points (-10,-4) and(-1,2) .
What is the y-intercept of the line?
a)(0,8/3)
b)(8/3,0)
c)(0,-4)
d)(-4,0)
