What is the equation of the line that has a slope of 3 and passes through the point (1, –2)?

Mathematics

lesya [120]3 years ago

Answer:

y = 3x - 5

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 )

Here m = 3 , thus

y = 3x + c ← is the partial equation

To find c substitute (1, - 2) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = 3x - 5 ← equation of line

Angie makes a spicy salsa by adding red pepper flakes to a chunky tomato mix in proportional amounts. For example she mixes 1/2
Nastasia [14]

Answer:

Please read the answer below.

Step-by-step explanation:

1. Let's represent the relationship between red pepper flakes, in teaspoons, to tomato mix, in cups in a table

Red pepper (teaspoons)   1/2    1    1 1/2   2  2 1/2   3  3 1/2   4  4 1/2   5      

Tomato mix (cups)              2     4       6     8    10     12   14     16   18    20

2. Let's represent the relationship between red pepper flakes, in teaspoons, to tomato mix, in cups writing a equation:

t = amount of tomato mix cups

r = amount of red pepper flakes teaspoons

As we can see in the table,

<u>t = 4r</u>

What number is 150% of 92
Setler79 [48]
The answer is 138 because 92 * 150= 13,900 and 1*100= 100.
Then you divide 13,800 by 100 and get 138.

So the answer is 138.

Hope that helped. :) :0 :p :D :d

Answer:

  1. b
  2. f
  3. e
  4. c
  5. h
  6. d
  7. g
  8. a

Step-by-step explanation:

< or > will give you an open dot which means it is not filled in.

≤ or ≥ will give you a closed dot which means it is filled in.

So for example number one:

x > 0 translated is x is greater than zero.

So look on the number line for an open dot on zero going toward the left (the side where the numbers get smaller). The rest are self explanatory.

WORTH 20 POINTS IF CORRECT! Write the slope-intercept form of the equation of each line show or explain your work. 1. is (0,4) (
Nookie1986 [14]

Answer:

1. y=5/2x+4

2. y=-7x-3

Y=mx+b is slope intercept form

Step-by-step explanation:

You have to add it in the slope intercept formula

2. M=-7   and B=-3

so y=-7x-3

M = 5/2       B = 4

So y = 5/2x+4
