1.  the slope of the line is rise/ run

pick two points  change in y/ change in x

we go up 7 and to the right 5

up and right are positive (down and left are negative)

  m = 7/5

2.  The y intercept is where we cross the  y axis  (x=0)

it is called b

b=7

(0,7)


3.  y=mx+b

y = 7/5 x+7

this is in slope intercept form

Y=-2x-5<br> y=5x+6<br> Round to the nearest hundredth.
yuradex [85]

Step-by-step explanation:

-2x-5=5x + 6

-2x - 5x = 6 + 5

-7x = 11

x = -11/7

x = 1.571

y = 5(1.571) + 6

y = 7.855 + 6

y = 13.855

Carrie is buying bulk candy for a high school fundraiser. She buys 1000 candy bars for $350. What is the unit cost per candy bar
liubo4ka [24]
1000 candy bars ... $350
1 candy bar ... $x = ?

If you would like to know what is the unit cost per candy bar, you can calculate this using the following steps:

1000 * x = 350 * 1
1000 * x = 350    /1000
x = 350 / 1000
x = $0.35

Result: She can buy 1 candy bar for $0.35, so the correct result would be B) $.35.
