Answer:

y = 2x + 3

Step-by-step explanation:

that's the equation

slope: 2

y-intercept: 3

Answer:

y=2x+3

Step-by-step explanation:

the equation of a line in slope intercept form is

y=mx+b where m is the slope and b is the y intercept

the graph crosses the y axis at 3, so the y intercept is 3

the line goes up 2 over 1, up 2 over 1, etc so the slope is

[tex] m = \frac{2}{1} = 2[/tex]

thus we get y = 2x + 3

Clyde is baking, and the recipe requires 1 1/3 cups of flour. Clyde has 2 cups of flour, but he is doubling the recipe to make twice as much. How much more flour does Clyde need? Write an equation to represent the problem. Let c represent the amount of flour Clyde needs, and then solve it.

Answers

Answer:

Clyde needs 2/3 cup more.

Step-by-step explanation:

The equation can be:

C = 2 - 2( 1   1/3 )

If Clyde is doubling the recipe, he will need 2 2/3 cups of flour. 2 2/3 minus 2 (the amount he has) will give you your answer.

A supermarket marks down the price of a $3.00 loaf of bread by 20%. What is the discount and the new price of the loaf of bread?

Answers

Answer:

new price= $2.40

Step-by-step explanation:

20%= 20/100= 1/5

$3.00/5= 00.60

1/5 of the price is being subtracted from $3.00

$00.60 is 1/5

3.00-.60= 2.40

Answer:

The discount is 20% off (you only have to pay 80% of the original price)

The new price of the bread is $2.40 (60 cents off)

Step-by-step explanation:

Because 20 goes into 100, 5 times I did 3.00/5

3.00/5= 0.6

Subtract 0.60 from the 3 dollars and that's it!

3.00-0.60= 2.40
