Write an equation of the line passing through the point (7,3) that is parallel to the line 4x-7y=9

y = -7/4x + 61/4

Step-by-step explanation:

Step 1: Write equation in slope-intercept form

-7y = 9 - 4x

y = 4/7x - 9/7

Step 2: Find slope of perpendicular line

Take the negative reciprocal of the 1st equation

m = -7/4

Step 3: Write out known variables

y = -7/4x + b

Step 4: Find b

3 = -7/4(7) + b

3 = -49/4 + b

b = 61/4

Step 4: Rewrite equation

y = -7/4x + 61/4

step-by-step explanation:

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
