Answer:
y = - 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (8, - 9) and (x₂, y₂ ) = (- 4, 15)
m = = = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, - 9), then
- 9 = - 16 + c ⇒ c = - 9 + 16 = 7
y = - 2x + 7 ← equation of line
12n-16.
12+12v.
-p-4.
-2x+8.
3x-21+7.
3-24x+4
The first thing to do is turn this into an equation:
2/3 ÷ 10
10 as a fraction is 10/1
2/3 ÷ 10/1 =
Fractional division is just fractional multiplication after switching the numerator and the denominator of the second fraction:
2/3 X 10/1
Fractional multiplication is simply multiplying the numerators by each other, and the denominators by each other:
2 X 10 = 20
3 X 1 = 3
20/3
Each piece of liquorice will be 20/3 or 6 2/3 of a yard long.
Answer:
I am going to say... B.
Step-by-step explanation:
I can't explain, it will take too long. I am not 100% sure, but I think I am correct. Please don't delete my answer, I am only trying to help.
Answer:
yes
Step-by-step explanation:
The standard form of a proportional equation is
y = kx ← k is the constant of proportionality
y = 10x ← is in this form and represents proportion.
