What is the equation of the line that is perpendicular to the line y = 1/3x + 7 and passes through the point (1, 5)?

y = -3x + 8

Step-by-step explanation:

The slope of a perpendicular line to the original equation is the opposite reciprocal of the slope of the original equation. This makes the opposite reciprocal -3, so the slope of the perpendicular line is -3.

Now that we have found the slope, we will put it into the formula for slope, y = mx + b. This results in getting y = -3x + b.

We know the values for x and y, (1,5) respectively. Plug these values into y = -3x + b.

5 = -3(1) + b

b = 8

This means that 8 is your y intercept and goes into place for b

Therefore, your resulting equation is y = -3x + 8

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
