1 What is the point-slope form of a line that has a slope of -4 and passes through point (-3, 1)?
=
oy-(-3) --4(x-1)
y-1--4[*-(-3))
-1-y, = -44-3-X)
3-y,--4(1-x)

Step-by-step explanation:

Given

Slope of line = -4

Point = (-3,1)

Required

Point slope equation of line

To get the equation of line, we make use of the following slope formula

Where m = -4 and

So; becomes

Multiply both sides by x + 3

Hence, the point slope form of the line is

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
