At an aquarium, researchers are preparing a mixture of salt water. the desired ratio is 90 grams of salt per liter of water.

1 ounce= 28.35

1 gallon= 3.8

what is the ratio in ounces per gallon

Step-by-step explanation:

we know that

The desired ratio is

step 1

convert grams to ounces

step 2

convert liter to gallons

step 3

substitute the values in the ratio

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
