What y-5>2x-10 looked like graphed
1 answer:
Answer:
Step-by-step explanation:
y-5>2x-10
put y on one side and rest on the other side of the > or greater than sign
to solve this
pretend > is an equal sign
y-5>2x-10
put +5 on both sides to get rid of -5
+5+y-5>2x-10+5
y>2x-5
for a quick graph use numbers that will give you quick y values like
x=0, reciprocal like 1/2 , numbers that will you get you 0 like 2.5 , 5 [and same in negative -1/2 , -2.5 , -5]
x=0 [y= -5]
positive
y>2x-5
x=.5 or 1/2 (so that 2x becomes 1) [y= -4]
x=2.5 (so that 2x becomes 5) [y= 0]
x= 5 [y= -5]
negative
y>2x-5
x= - .5 or - 1/2 (so that 2x becomes -1) [y= -6]
x= -2.5 (so that 2x becomes 5) [y= -10]
x= -5 [y= -15]
quick plot points
(0,-5) , (1/2,-4) , (2.5,0) , (- 1/2, -6) , (-2.5, -10) , (-5, -15)
