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.
Answer:
x=16
Step-by-step explanation:
If you are using a calculator, simply enter 20×100÷125, which will give you the answer.
We have, 125% × x = 20
Multiplying both sides by 100 and dividing both sides by 125,
we have x = 20 × 100/125
