Write an equation of the line that passes through the point and has the given slope. Write the equation in slope-intercept form.

yulyashka [42]

The slope is already given in the question, so we only ned to solve for the y-intercept using y = mx + b.

4 = 3(1) + b

4 = 3 + b

4 - 3 = 3 + b - 3

1 = b

Now, write the equation in slope-intercept form.

y = 3x + 1

Step-by-step explanation:

Given: Microscopes. Each one costs $200 and resells online for $526.

To find: What is the mark-up percentage?

Solution: Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

$526 - 200 = 326$
