Write the equation of the line that passes through the points (4,-6) and (-2,3)
yarga [219]

Here is your answer and an explanation

Answer: y = -2/3x

Explanation:

This can be determined by calculating the gradient of the straight line, using:

m=ΔyΔx

=−6−34−(−2)

=−96

=−32

Then we use the slope-point form of the straight line:

y−y1=m(x−x1)

to give:

y−3=−32(x−(−2))

∴y−3=−32(x+2)

∴y−3=−32x−3

∴y=−32x

1.) Last year, Diane biked k miles. This year, she biked
Naddika [18.5K]

Answer:

1.) k + 516

2.) 2n - 4 = 3

3.) 57 - 2s

4.) 9h = 153

5.) c = 5n

Step-by-step explanation:

All of the problems given require you to set up an expression or equation.  Expressions have a variable and a coefficient or a constant.  Equations also have a variable, coefficient or constant but also include an equal sign.

1.) last year's miles = k, this year = 516, so total:  k + 516

2.) twice the difference of a number and 4 equals 3

twice a number = 2n; difference of this number and 4: 2n - 4; equals 3: =3

2n - 4 = 3

3.) 57 decreased: 57 -; twice her savings: 2s:  57 - 2s

4.) 153 is:  153 =; the product of height and 9:  9h, so 9h = 153

5.) notebooks 'n', were $5 each:  5n; total cost = c, so 5n = c
