Y=mx+b (-6,-3) and (0,9)

Mathematics
1 answer:
Leno4ka [110]3 years ago

Answer:

y = 2x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 6, - 3) and (x₂, y₂ ) = (0, 9)

m = \frac{9+3}{0+6} = \frac{12}{6} = 2

The line crosses the y- axis at (0, 9) ⇒ b = 9

y = 2x + 9 ← equation of line

igor_vitrenko [27]
Answer: 143 hamburgers and 429 cheese burgers

Explanation:

Call h and c the number of both items.
(h-hamburger and c-cheeseburger)

h + c = 572
c = 3h

Sub the second into the first

h + 3h = 572
4h = 572

Divide both sides by 4
h = 143 hamburgers

Use this back into the second equation
c = 3 • 143 = 429 cheeseburgers

What is the slope of the line ?
svetlana [45]

Answer:

y = -3x + 4

Step-by-step explanation:

y = 4, this is where your line intersects with the y axis.

x = 1 is where your line is on the x axis (you want to include the part of the line that hits a point straight on, not one that goes past it.) So when it lands on the corner of the grids like the 4 for the y axis does, that is the point you are going to use.

Rise/Run is then your equation, so since you go down 3 and over 1 (counting from your y axis point), your slope is -3/1 or -3.

Then goes your y axis, so the final equation is

y= -3x + 4

I hope this helped!

Solve this pls <br> 5) 3x6-4=?
lina2011 [118]

Answer:

5

Step-by-step explanation:

Use PEMDAS to complete the problem

PE doesn't matter, there's not parentheses or exponents

MD=Multiplication and Division. Do 3*6=9, now your problem looks like 9-4

AS=Addition and Subtraction. 9-4=5
