Somebody please help me I do anything look below for the question

y = 2x - 7

Step-by-step explanation:

okay so for linear eqns you need to find the gradient + y-intercept

y-intercept is when x = 0, in this case it is -7

now that you have the y intercept for the gradient you can either use substitution or the normal rise / run

substitution :

because we already have some other value pairs so let's use x = 2, y = -3, remember we're trying to find the m of mx + c (c = -7)

m(2) - 7 = -3

2m = 4

m = 2

we can use the other sets to confirm:

2(4) - 7 = 1

2(6) - 7 = 5

rise over run:

just take any 2 sets and find the difference in x and y and let's say I use x = 4 and 6, y = 1 and 5. now find diff. between the ys / diff. between the xs

gradient = (5-1) / (6-4)

so gradient = 2, and eqn is y = 2x - 7

hope this helps yeet

c

step-by-step explanation:

c

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
