Mathematics
1 answer:
PtichkaEL [24]3 years ago
5 0

Answer:

a) y=2x+4 b) 2 c) 6 d) Sorry, you'll have to do that buy it's not too difficult! ^u^

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

1a) Well, if you add the y to both sides, you would get y=2x+4

1b) Since the main form is y=mx+b with m being the slope, the slope in y=2x+4 must be 2

1c) 6, because if x is 1, 2(1)+4=6

1d) I'm afraid you'll have to do that, just substitute in different numbers for x

(っ◔◡◔)っ ♥ Hope this helped! Have a great day! :) ♥

Please, please give brainliest, it would be greatly appreciated, I only need one more before I advance, thanks!

What does a decimal between two fractions mean
Anni [7]

Answer:

Multiplication

Step-by-step explanation:

I think what you're talking about is not a decimal, but a multiplication point:

\frac{1}{2} \:  . \:  \frac{3}{4}

This dot can donate multiplication when in the middle of two numbers and/or fractions.

But if you're talking about some other point, then I don't know, sorry. :(

Find the lines slope and a point on the line.
sesenic [268]

Answer:

The slope is  3/4 and a point on the line is (-5,2)

Step-by-step explanation:

This is given in point slope form

y - y1 = m(x-x1)

where m is the slope and (x1,y1) is a point on the line

y-2 = 3/4(x +5)

y-2 = 3/4(x - -5)

The slope is  3/4 and a point on the line is (-5,2)
