uysha [10]

Answer:

y = \frac{4}{3} x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (6, 10) ← 2 points on the line

m = \frac{10-2}{6-0} = \frac{8}{6} = \frac{4}{3}

The line crosses the y- axis at (0, 2 ) ⇒ c = 2

y = \frac{4}{3} x + 2 ← equation of line

What is the value of x?
alexira [117]
U have an equilateral triangle where all angles are equal to 60 degrees

7x + 4 = 60
7x = 60 - 4
7x = 56
x = 56/7
x = 8 <==

and if u wanted to find y, u would set it up like this : 8y + 12 = 60 and solve for y

Choose the slope-intercept form of 3x + 2y = 5
wlad13 [49]

Answer:

y = -3/2x + 5/2

Step-by-step explanation:

slope intercept form is y = mx + b

so we have to solve the equation for y

2y = 5 - 3x

y = 5/2 -3/2x

or

y = -3/2x + 5/2

Please help me solve this! I’ve been stuck for ages! Thankyou

Answer:

y = sin(x- pi/2)

Step-by-step explanation:

Please see the attached image to see your graphs.

By simple inspection we can see that the sine is shifted pi/2 to the right.

We know this because sines are periodic functions with a period T = 2*pi

We can also see that the maximum point of the graph (y = 1) got shifted by a fourth of the period.

And finally, since we want to shift the graph to the right, we need to substract from the argument of the sine term.
