Write an equation that will model the proportional relationships shown in the graph below graph.

Answer:
y = 5x
Step-by-step explanation:
you can use the Slope-Intercept form of a line, which is:
y = mx + b where 'm' is the slope, and 'b' is the y-intercept
to find the slope, select any two points:
we can use (0,0) and (2,10)
now subtract the y-values and the x-values to get this fraction:
slope = 10-0 / 2-0
slope = 10/2 or 5/1
the y-intercept can be seen and is 0
therefore, equation of this line is:
y = 5x + 0 or
y = 5x
