The standard equation of a line is given by:
y = mx + b
Where,
m: slope of the line
b: intersection with the y axis.
To define the linear function you need to know the value of the constants m and b
Answer:
You need in order to find an equation:
Slope of the line
Cutting point with the y axis

Karrem says that the ratio 4:1 is eqivilent to the ratio of 12:9 because 4+8=12 and 1+8 =9 is karreem correct

Mariana [72]

Answer:

No, Kareem is incorrect.

Step-by-step explanation:

Kareem says that the ratio of $\frac{4}{1}=\frac{12}{9}$ because 4 + 8 = 12 and 1 + 8 = 9

But the correct way to rewrite the ratio 4 : 1 is,

$\frac{4}{1}=\frac{4\times 3}{1\times 3}$

Which becomes as,

$\frac{4}{1}=\frac{12}{3}$

Therefore, Kareem is not correct.

Correct ratio equivalent to 4 : 1 is 12 : 3.

Lisa is on a trip of 887 miles. She has already traveled 98 miles. She has 3 days left in her trip. How many miles does she need

STALIN [3.7K]

I might be wrong but, I would say about 32.6 miles a day. This could be wrong.

Solve the system of equations by graphing. <br><br> x+y=3<br> y=2x−15

Stella [2.4K]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

x + y = 3

x = 3 - y

y = 2x - 15

y = 2(3 - y) - 15

y = 6 - 2y - 15

y = -2y - 9

3y = -9

y = -3

y = 2x - 15

-3 = 2x - 15

-2x = -12

x = 6

So...

The answer is: (6, -3)
