A number Y is five times the value of a number X. A lion graft in a coordinate plane represents the relationship between X and Y
zepelin [54]

Answer:

5

Step-by-step explanation:

y=5x

Compare this with the slope-intercept form of the equation of a line.

y=mx+b  where <em>m</em> is the slope and <em>b</em> is the <em>y</em>-intercept.

The value of <em>m</em> is 5.  The slope is 5.
