Answer 1

that's a grahph fyi

Answer 2

no

Answer 3

what @henryli

Answer 4

Okay so a graph with points

(2,5)
(4,10)
(6,15)
(8,20)

So...we have at least 2 points...so lets find the slope...

Lets take (2,5) and (4,10)

Let
2 = x1
4 = x2
5 = y1
and
10 = y2

\[\large slope = m = \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 5

thank you @johnweldon1993

Answer 6

And then with that slope 'm' plug that and any 1 point (Xo,Yo) into the point slope formula

\[\large y - y_0 = m(x - x_0)\]

Answer 7

okay
