Question 947675
graph the linear function y= -3/4x +4 explain any key points including intercept, vertex. state the domain and range and write it in interval notation and is it a function or not
***
{{{y=-3x/4+4}}}
This is an equation of a line: y=mx+b, m=slope, b=y-intercept
function? yes
x-intercept:
set y=0
3x/4=4
3x=16
x=16/3=5 1/3
..

y-intercept=4
..
slope=-3/4
domain: (-∞,∞)
range(-∞,∞)
..
vertex: NA
