Work out the equation of a line which has a gradient of -2 and passes through the point (1 ,7)​

Mathematics
1 answer:
r-ruslan [8.4K]3 years ago

Answer:

Y=-2x+9

Step-by-step explanation:

The first thing is to know the formula which is Y÷x

Then... The line (1,7)use the coordinates Y and X so it will be as follows... Label 1 and 7 as x, y

So it will be Y-7÷X-1 = the gradient which is - 2

So multiply both sides by X-1

So it will be Y-7=2x+2 again be careful because a negative number multiplied by another negative will give you a positive sign

Remember Y-7....... Take 7 to the other side so it will be a positive...... Then work out the integers

Lilian says that 25% of a number will always be less than 75% of any other number. Complete one inequality to support Lillian's
rjkz [21]
She is incorrect cause if we take the number 20 and take 25% of it it equals 5 so now 20 is only 15. They if we take 75% away from 20 is equals 15 so then we only have 5 from 20 left. Therefore she’s incorrect because 75% leaves 5/20 and 25% leaves 15/20. Hope that makes sense.

Sam and Harry are family. Sam is currently is three times Harry's age. Sam's age is also 10 more than twice Henry's age. What ar
kramer

Answer:

<em>Sam is 30 years old, and Harry is 10 years old.</em>

Step-by-step explanation:

Let us assume that the age of Sam is x and the age of Harry is y.

Sam is currently is three times Harry's age.

So, x=3y  ----------------------1

Sam's age is also 10 more than twice Harry's age.

so, x=2y+10  ---------------2

Subtracting 2 from 1, we get

\Rightarrow x-x=3y-2y-10

\Rightarrow 0=y-10

\Rightarrow y=10

putting this in equation 1,

x=3(10)=30

Therefore, Sam is 30 years old, and Harry is 10 years old.
