System of equations y=2x+3 y=2x+1

y=2x+3 y=2x-1. y=2x+3 y = 2 x + 3 y=2x−1 y = 2 x - 1.

Step-by-step explanation:

Marissa created a graph with no of months since hair cut on x axis, and inches in growth as y axis.

The graph is a straight line showing the slope is a constant

The line starts with (0,0) showing that equation is

y =mx for some m

Consider any point on the graph.

(say) (2,1.5)

When x=2, y =1.5

i.e. 1.5 = 2m

Or m =0.75

Hence the line is y = 0.75x

The table corresponding to this graph would be

x    0    1        2     3       4    5      6

y     0  0.75  1.5  2.25  3  3.75  4.5
