I think it's: 2 ( w - 5 ) . The grammar makes it hard.

3x+4=y+5, then y+5=3x+4
It is called: reflexive property

Graph the function represented in the table on the coordinate plane.

Umnica [9.8K]

First find out the function for the given table.
Find the slope.
m= (y2-y1)/(x2-x1)
m=(-1-(-3)) / (-1-(-2))
m=(-1+3) / (-1+2)
m=2/1
m=2
Now equation of line:
y-y1=m(x-x1)
y-(-3)=2(x-(-2))
y+3=2(x+2)
y+3=2x+4
y=2x+1
Now plot these points on the graph, we get the attached graph.
