Answer:
Slope = 2/7
y-intercept = 0
Proportional = yes
It is proportional since we require no additional terms to get y from x and we can multiply each x term by a certain factor to get the y values
Explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope and b is the y-intercept
From what we can see, the slope of the given line is 2/7
As we can see, there is no y-intercept; so the y-intercept value is 0
As we can see, we can multiply each x value by 2/7 to get the corresponding y-value
What this mean is that both variables are proportional
