Write the equation of the line that passes through the points (-1, 2) and (6, 3) in slope-intercept form. Step 1: Choose (X1,Y1)

Ivan

Answer:

Step-by-step explanation:
Given that the line passes through two points (-1,2) and (6,3)
Slope of the line passing through (x1,y1) and (x2,y2) is y2-y1
x2-i1

Hence slope of our line =
(3-2)/(6+1) = 1/7
So in slope intercept form the equation would be
y = 1/7 x +C
to find C
Since (-1,2) lies on the line substitute these in the line equation
2 = 1/7(-1)+c
C = 2+1/7 = 15/7
Hence equation in slope intercept form is y=x/7+15/7

What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of −56 ?

olga55 [171]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the point (8, -4) and the slope m = -56. Substitute:

$y-(-4)=-56(x-8)\\\\\boxed{y+4=-56(x-8)}$

Need help bad please will mark brainliest

katrin [286]

Answer:

(-3, 5), (4, 1), (-1, -5)

Step-by-step explanation:

270° counterclockwise rotation is same as 90° clockwise

The rule is:

(x, y) → (y, -x)

Given points:

A(-5, -3), B(-1, 4), C(5, -1)

Translated points:

A' = (-3, 5)
B' = (4, 1)
C' = (-1, -5)

Use demovires theorem to write the complex number in trigonometric form.

Anastasy [175]

$\sqrt3+i=2\left(\dfrac{\sqrt3}2+\dfrac12i\right)$

$\begin{cases}\cos\dfrac\pi6=\dfrac{\sqrt3}2\\\\\sin\dfrac\pi6=\dfrac12\end{cases}$

$\implies\sqrt3+i=2e^{i\pi/6}$

By DeMoivre's theorem,

$(\sqrt3+i)^3=(2e^{i\pi/6})^3=8e^{i\pi/2}=8\left(\cos\dfrac\pi2+i\sin\dfrac\pi2\right)=8i$
