Answer:

28 and 37

Step-by-step explanation:

This is very simple actually!

First subtract the 9:

65 - 9 = 56

Then divide by 2:

56 ÷ 2 = 28

28 is one of your answers. If we want to find the other one, then add back 9

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

Answers

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
