Answer:

y = 3x + 3

Step-by-step explanation:

If the entire line, or rather, the graph, is translated upwards by 5 units; the slope stays the same, but the y-intercept rises by 5 as well. Thus, the equation of the new graph would be;

y = 3x (-2+5)

y = 3x + 3

Answer:

y = 3x + 3

Explanation:

Let's say you put a point or line on a graph at (2, 3) with 2 being the x-axis, and y being the y-axis, when you translate it left or right, you would move the point or line left or right, which changes the x-axis. If you move it to the right, you would increase the x value, and decrease it if you move it to the right. This is the same thing for going up and down. moving it up increases the y value, and moving it down decreases the y value.

When you place an equation on a graph, y is the result or point on the line when x equals a certain number. If x equaled 3, then the equation would be, y = (3 * 3) - 2. Which would be 9-2 = 7.

The 3x is the slope of the line, for every 1 unit to the right, the line would go 3 units up. the -2 is the intersection of the line through the y axis. so in this equation, the intersection would be -2.

To find the new equation, you would take the first equation, y = 3x - 2, then when you translate it up, you would increase the y intersect of the line by however much you need to, which would be 5. so you would just add 5 to the -2 to get the new equation. So now the new equation you have is y = 3x +3.

Mr. jovanovski is having wood flooring put in his rectangular living room. the area of the room is 234 square feet. the length o
OlgaM077 [116]
By definition the area of a rectangle is:
 A = l * w
 Where,
 l: long
 w: width
 So we have to clear the width:
 w = A / l
 Substituting the values:
 w = (234) / (18) = 13
 w = 13 feets
 answer
 the width, in feet, of the room is 13

Find 5 consecutive integers whose sum is 244
storchak [24]

So the first integer is 61.

Then the others must be 62, 63, and 64. To check, you can add them all together. 61+62+63+64=250.

Ali has q quarters. Tom has four more quarters than Ali.
Anna35 [415]

Answer: x(.25)+(4+x(.25))=y

Step-by-step explanation:

1. set up the equation-

Ali has an unknown amount of quarters so make that x.

We know quarters are 25 cents so .25 if he has one quarter you put that one quarter into x, 2 into x and so on

Tom has 4 more, since he has 4 more it is 4+x and one again times .25

2. that is it
