Which equation could have been used to create this graph? y = 2x y = x + 4 y = 4x y = x + 2 a coordinate graph. the horizontal axis is labeled x and ranges from 0 to 10. the vertical axis is labeled y and ranges from 0 to 25. a line connects the points plotted at begin ordered pair 0 comma 0 end ordered pair, begin ordered pair 1 comma 4 end ordered pair, begin ordered pair 2 comma 8 end ordered pair, begin ordered pair 3 comma 12 end ordered pair, begin ordered pair 4 comma 16 end ordered pair, begin ordered pair 5 comma 20 end ordered pair, and begin ordered pair 6 comma 24 end ordered pair.

y =4x

Step-by-step explanation:

points (0,0)   (1,4) (2,8) (3,12)  (4,16) (5,20)  (6,24)

slope = (y2-y1)/(x2-x1)

        = (4-0)/(1-0)

        =4/1

 = 4

the slope it 4

the y intercept is 0  ( where it crosses the y axis)

the slope intercept form of an equation is

y= mx+b

y = 4x+0

y =4x

Look at the picture.

The slope-intercept form:

m - slope

b - y-intercept

From the graph wi have the y-intercept b = 0. Therefore the equation of a line is

The slope

We can calculate the slope:

We have two points (0, 0) and (1, 4). Substitute:

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
