Mathematics

zysi [14]2 years ago
4 0

Answer:

<u>Answer</u><u>:</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>2</u><u>x</u><u> </u><u>+</u><u> </u><u>8</u>

Step-by-step explanation:

• General equation of a line:

\hookrightarrow \: { \rm{y = mx + b}}

  • m is slope / gradient
  • b is y-intercept.

[ for parallel lines, slopes are the same ]

• m is 2

{ \rm{y = 2x + b}}

for point (-2, 4)

{ \rm{4 = (2 \times  - 2) + b}} \\  \\ { \rm{4 =  - 4 + b}} \\  \\ { \rm{b = 8}}

• therefore, equation is:

{ \boxed{ \rm{y = 2x + 8}}}

How to find the long side of a right triangle that has two same short side?
Nataliya [291]
To find the hypotenuse of a right triangle, you must use a^2 + b^2 = c^2

* keep in mind the hypotenuse MUST be larger than the legs.

The Pythagorean Theorem comes from making 2 squares from the lengths of each leg (that is why it is a^2 and b^2). The hypotenuse must be equal to the area of the two squares created.
