What is the equation of the line that passes through the point (8,-4) and has a slope of 3?

2 answers:

8 0

In order to solve it you insert the point in slope from

the equation is
Y=Mx+b

Plug it in as

-4=3(8)+b

-4=24+b

Then subtract 24

B=-28

So

The answer is

Y=3x-28

Y-y1=m(x-x1)

(8, -4) 8 is x1 and -4 is y1
so y- (-4) = 3 (x -8)
make 4 a positive then y + 4 = 3x - 24
subtract 4 from 24 then y=3x-20

A baseball team played 154 regular season games. The ratio of the number of games they won to the number of games they lost was

ELEN [110]

Answer:

Number of games won = 110

Step-by-step explanation:

Given:

Total games played = 154

The ratio of number of games won to number of games lost = $\frac{5}{2}$

Solution:

Let the number of games won be = $5x$

Thus, number of games lost = $2x$

The total games played can be given as = $5x+2x=7x$

Thus, we have:

$7x=154$

Dividing both sides by 7.

$\frac{7x}{7}=\frac{154}{7}$

∴ $x=22$

So, number of games won = $5\times 22 = 110$
