Answer:

y = 10x + 15

Step-by-step explanation:

you pick two points on the line

I picked (3,45) and (6,75)

you subtract the two x’s and y’s

75 - 45 = 30 (30 is the rise) you go up from 45 to 75

6 - 3 = 3 (you move 3 times to the right to get to the 6) so 3 is the run

slope = rise/run so 30/3 = 10

The y-intercept is the place you start on the graph so that is 15

Please prove the following trigonometric identity.<br><br>​
Brums [2.3K]

Step-by-step explanation:

solution:- from LHS 1-cos²x/sinx

∵ 1-cos²x = sin²x

∴ sin²x /sinx = sinx

from RHS tanx × cosx

∵tanx = sinx×cosx

∴ sinx/ cosx × cosx = sinx

Since, LHS = RHS proved ___

What is the slope of the line whose equation is 2x−4y=10 ? Enter your answer in the box. NEED HELP ASAP PLEASE WILL GIVE BRAINLI
stich3 [128]

Answer:

The slope of the line is 1/2.

Step-by-step explanation:

2 x − 4 y = 10 (Subtract  2 x from both sides.)

− 4 y = − 2 x + 10 (Divide both sides by -4.)

y = − 2 x − 4 + 10 − 4  (Simplify.)

y = 1/2 x − 5 /2

y=1/2
