Find an equation of a line with the x- and y-intercepts below. Use exact fractions when necessary.
tamaranim1 [39]

Answer:

y=\frac{5}{7}x-5

Step-by-step explanation:

All lines in the plane are of the form

y = mx+b

<u><em>The intersection with the Y-axis is obtained by replacing x with 0 </em></u>

<u><em>The intersection with the X-axis is obtained by replacing y with 0 </em></u>

If we want that the Y-intercept = -5, then  

-5 = m(0)+b

So b = -5

Our temporal equation is then

y = mx-5

If we want that the X-intercept = 7, then  

0 = m(7)-5

7m = 5

m = 5/7

So our final equation is

y=\frac{5}{7}x-5

Attached is the graph of the line

Which teacher exhibited the most variable year to year performance over this 5 year span?
Tanzania [10]

<u>Answer-</u>

Ed exhibited the most variable year to year performance over this 5 year span.

<u>Solution-</u>

Most variable performance means varying performance or non-consistence performance.

As shown in the graph,

Jill's performance was constant throughout 2005-07.

Ralph's performance was constant throughout 2006-07 and also in 2008-09.

Tina's performance was constant throughout 2007-09

Sam's performance was constant throughout 2008-09.

All of them has been consistence for at-least once. But, in case of Ed, throughout the time, his performance was in-consistence or variable.

Maggie's brother is 6 years younger than four times her age. The sum of their ages is 69.
Tomtit [17]

Answer:

15

Step-by-step explanation:

If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,

4x-6+x=69

5x-6=69

5x=75

x=15

So, Maggie is 15.
