10) (9,-3); m=2

(a) y=2x-11
Plug in the variables that are constant on both the given line and the new one.
y=mx+b

-3=2(9)+b

Do not input b, as the y intercept is relative to the specific line, and not others.

-3=18+b
-3-18=b
-21=b

The y intercept of the new line is -21.

FINAL ANSWER::y=2x-21

(b) y=2x-21
Plug in the variables that are constant on both the given line and the new one.
y=mx+b

-3=2(9)+b

Do not input b, as the y intercept is relative to the specific line, and not others.

-3=18+b
-3-18=b
-21=b

The y intercept of the new line is -21

FINAL ANSWER::y=2x-21
Or equivalent to the original.

Hope this helps you solve the rest. ;)

Find the missing length of the triangle.
allsm [11]

Hey there!

Solve using pythagoras theorem (it's given that is triangle is right angled. Pythagoras theorem only works in the case of right triangles) ⇨ Hypotenuse² = Base² + Altitude ²

Here,

Base = 9 mm

Hypotenuse = 15 mm

Altitude = b

Hypotenuse² = Base² + Altitude ²

15² = 9² + b²

225 = 81 + b²

225 - 81 = b²

144 = b²

√144 = b

<u>1</u><u>2</u><u> </u><u>mm </u>= b

Hope it helps ya!
