I have gotten graph questions but Im not sure how the questions match to the graph because I can solve the questions without it?
Can anyone help?

how do I work out the questions with the gra[h

question 7 is
I have a number times 2 (2x) and then subtract 1 (2x-1)
then this is equal to 4, note there’s a graph 2x-1 and you find at which x value it’s equal to 4

#

however I don’t recommend this method as there isn’t a really good way to get the exact fraction or be sure if your value is an integer or not

#

for example here’s a graph that kind of looks like it kind of is a lattice point

#

however it’s not

#

so only use it as a rough estimate to check your normal algebraic work
