The slope is B. 5/2

Slope is change in y/change in x.
Pick 2 sets of points and plug in.
For example, (0,3)(2,8) would be 8-3/2-0=5/2

M=0 passing through p(-2,-2)
valentinak56 [21]

Answer:

The equation of line is y+2=0

Step-by-step explanation:

The equation of line passing through the point (x_{1},y_{1} )and having slope  m is

y-y_{1} = m (x-x_{1}

Given slope m=0 and given point is  is (-2,-2)

y-(-2)=0(x-(-2))

y+2=0

therefore equation of the straight line is y+2=0

Therefore the straight is parallel to negative x-axis(y=-2)

olivia has $180 to buy presents for her 3 sisters and 2 nephews. She wants to spend $15 more on each sister than she spends on e
koban [17]
So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y

she wants to spend 15 dollars more on sisters than nephews
so
x=15+y
solve

we have
180=3x+2y and
x=15+y
subsitute 15+y for x

180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y

solve for x
x=15+y
x=15+27
x=42

she spent $42 on each sister

A bike shop rents each of its mountain bikes for a one time $4.00 insurance charge plus $2.50 per hour create an equation that r
egoroff_w [7]

Answer:

y=2.50x+4.00

Step-by-step explanation:

Let

x -----> the number of hours

y ----> the total cost to rent a bike in dollars

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope or the unit rate of the linear equation

b is the y-intercept or the initial value

In this problem we have

The unit rate or slope is equal to

m=\$2.50\ per\ hour

The y-intercept (value of y when the value of x is equal to zero) is equal to

b=\$4.00 ----> (fee charge)

substitute the values

y=2.50x+4.00
