Question 170589This question is from textbook
: y=-1/2x+5/2This question is from textbook
: y=-1/2x+5/2
Answer by jojo14344(1023) About Me  (Show Source):
You can put this solution on YOUR website!
y=(-1/2)x+(5/2) ---------> this follows Slope-Intercept form, y=mx+b
Slope=m=(-1/2) & Yintercept=(5/2)
f(y)=0
(1/2)x=5/2 --->cross(1/2)x/cross(1/2)=(5/2)/(1/2)
x=(5/cross(2))(cross(2)/1)=5, x-intercept
See graph:

y=-1/2x+5/2
y=-x/2+2.5
The line equation is:
Y=mX+b where m=slope & b=y intercept.
This line has a slope(m)=-1/2 & a y intercept (b)=2.5.
