I think you mean how do you find linear equations. It is actually very simple when you memorize the formula. Linear equations are in the form of y = mx + b. m is the slope. b is the y-intercept.
ex. given: slope = 5, y-intercept = -3: our equation is y = 5x - 3
We know there are 12 months in a year so we would multiply 1 1/4 by 12. We can write 1 1/4 as 1.25 (to make it easier to multiply). 12x1.25=15 Your answer is 15 vacation days in one year
At three hours as car a has already traveled a hour which making it three therefore making car b equal 2 hours or in a math equation 40×3=car b and 60×2=car a
