What is the y-intercept of this line?<br> y = =+5<br> b = [?]

vaieri [72.5K]

Answer:

b = 5

Step-by-step explanation:

Slope-Intercept form: y = mx + b

<u>where:</u>

m is the slope
b is the y-intercept (when x = 0)

$\sf \textsf{Given:}\ \dfrac{-4x}{3}+5$

$\sf \textsf{slope:}-\dfrac{4}{3}$
$\sf \textsf{y-intercept:}\ 5$

Therefore, the value of b is 5.

Translate the following into an algebraic expression:

kaheart [24]

Answer:

2(n-9)

Step-by-step explanation:

Hi there!

Let "a number" = n.

"The difference" translates to subtraction, so when the question tells us "the difference of a number and 9", it translates to "n-9".

"Twice" means we'll be doubling something. In this case, we're doubling "n-9":

2(n-9)

I hope this helps!
