SOLUTION: A direct variation equation is an equation in slope-intercept form which describes a line that passes through the origin. Suppose that the points (-45,33) and (k,253) are also on t

Question 1058458: A direct variation equation is an equation in slope-intercept form which describes a line that passes through the origin. Suppose that the points (-45,33) and (k,253) are also on the line. Write the equation of the line and give the value of k using the equation.

Thanks!

Since you know it goes through the origin, you can calculate the slope with the given point and the origin,

So using the point slope form,

So then,
