When it's laid out like that. 2 division statements on either side with one unknown variable you just cross multiply really easy
5 x 24 / 6 = 20
Take the number that's on the same position of the x thats 5 then multiply it to the numerator or denominator of the x thats 24 then divide it to its denominator thats 6
Answer: The slope of the line is 15 and y-intercept is 12.
Step-by-step explanation: We are given to find the slope and y-intercept of the straight line defined by the points (3, 57) and (5, 87).
We know that
the slope of a line passing through the points (3, 57) and (5, 87) is given by

Since the straight line passes through the point (3, 57), so its equation will be

So, the required equation of the straight line is 
Thus, the slope of the line is 15 and y-intercept is 12.
