If we want to figure out the ages of Octavia and her brother we will need to check our information.
their ages add up to 39 and her brother is 7 years older than her 
first you will think of all numbers that equal 39; 1+38, 2+37, 3+36, 4+35, 5+34, 6+33, 7+32, 8+31, 9+30, 10+29, 11+28, 12+27, 13+26, 14+25, 15+24, 16+23, 17+22, 18+21,and 19+20
then  eliminate all the numbers that don't have a difference of 7 which will leave the following; the only numbers left are 16 and 23 

so that means that her brother is 23 and Octavia is 16

For the answer to the question above asking, w<span>hat was the price per can and the numbers of cans purchased each time?

the let us go to the 2nd statement which is t</span><span>he next time Ian purchased frozen orange juice, the price had increased by $0.10 per can and he bought 1 less can for the same total price.
The equation for this is .10(x-1) = 24
So now let's solve, 
</span> .10(x-1) = 24
.10x - .10 = 24
.10x = 24+ .10
.10x = 24.10
Then divide both sides by .10
So the answer for this question is 
241 cans of juice

A line has a slope of 8 and a y-intercept of 0 what is its equation in slope intercept form
Deffense [45]
Slope-intercept form is y = mx + b.
In this form, m is slope and b is y-intercept.
Slope is rise over run. The formula for this is (y2-y1)/(x2-x1).
Y-intercept is the value of y when x is equal to 0.

1. Slope = 8 ; Y-intercept = 0
y = mx + b
m = 8 ; b = 0
y = 8x + 0
y = 8x

2. Slope = 1 ; Y-intercept = 2
y = mx + b
m = 1 ; b = 2
y = 1x + 2
y = x + 2

The answer to #1 is y = 8x.
The answer to #2 is y = x + 2.

Hope this helps!
