Y=mx+b

Y= -2/3X - 2

Y= -5/2x + 2

Use PEMDAS

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

$7-8\div4\cdot(3^2-1)=7-2\cdot(9-1)=7-2\cdot8=7-16=-9$

Which is the equation of the given line in slope-intercept form? (-1, 2) and (1, -4)

Natalka [10]

1. Find the slope using the slope formula.
$\frac{2 - ( - 4)}{ - 1 - 1} = \frac{2 + 4}{ - 2} = - \frac{6}{2} = - \frac{3}{1} = - 3$
2. Plug that slope and either point into an equation in slope-intercept form and solve for b.
$2 = - 3( - 1) + b \\ 2 = 3 + b \\ - 1 = b$
3. Now write your answer as a slope-intercept form equation
$y = - 3x - 1$

Quick! 8 points! best answer is brainiest!

Novosadov [1.4K]

What I understand from the picture given, she had 2 ribbons with the length of 1/4.
These would be the two shortest ones.
So: 1/4 + 1/4 = 2/4
= 1/2

I hope this helps and I know that it is different to what HimyBrainy put but it is what I understood! :/
