Answer:

The y-intercept of our given line = 1.

Step-by-step explanation:

We have been given that a line passes through the points (8,-1) and (-4, 2). We are asked to fine the y-intercept of the line.

We will use slope-intercept form of equation to solve our given problem.

y=mx+b, where,

m = slope,

b = y-intercept.

Let us find the slope of our line using slope formula.

m=\frac{y_2-y_1}{x_2-x_1}, where,

y_2-y_1=\text{The difference between two y-coordinates}

x_2-x_1=\text{The difference between x-coordinates of same two y-coordinates}.

Upon substituting coordinates of our given points in slope formula we will get,

m=\frac{-1-2}{8--4}

m=\frac{-3}{8+4}

m=\frac{-3}{12}

m=-\frac{1}{4}

Upon substituting m=-\frac{1}{4} and coordinates of point (8,-1) in slope-intercept form of equation we will get,

-1=-\frac{1}{4}*8+b

-1=-1*2+b

-1=-2+b

Let us add 2 to both sides of our equation.

-1+2=-2+2+b

1=b

Therefore, the y-intercept of our given line is 1.

F=5/4(n-90)<br> Find n <br> Helppp
padilas [110]

Answer:

n= 4f/5+90

Step-by-step explanation:

f=  ​5(n−90) /4 (simplify)

f * 4=5(n−90)  (multiply 4 on both sides)

4f=5(n−90)  (regroup)

4f/5 ​​ =n−90 (divide 5 on both sides)

4f/5 ​​ +90=n  (add 90 to both sides)

A store pays $10.56 fora map of Africa and marks the price up by
nignag [31]

Essentially, 50% of $10.56 is $5.28.

This means that all we have to do is add $10.56 to $5.28, making <u>$15.84</u>


Side note: Another way that you can do this is by simply doing 1.5(10.56).
