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

How does f(4) if f(x) = 2x work? how do i work this out?

sveta [45]

So just plug in the 4 wherever you see an x. so it is f(4)=2(4)

M=0 passing through p(-2,-2)

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
