Answer:

A) y=-6x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-17-(-5))/(3-1)

m=(-17+5)/2

m=-12/2

m=-6

y-y1=m(x-x1)

y-(-5)=-6(x-1)

y+5=-6(x-1)

y=-6x+6-5

y=-6x+1

Answer:

y=1/3x+4

Step-by-step explanation:

y=mx+b

(0,4) and (-4,-8)

use the slope formula to find the slope between these two points:

(-4-0)/(-8-4)

the slope is 1/3.

y=1/3x+b

plug in one of the points. I used (0,4).

4=1/3(0)+b

4=b

y=1/3x+4

Use Heron's Area Formula to find the area of the triangle. (Round your answer to two decimal places.) A = 79°, b = 77, c = 43

Answer:

1549.5

Step-by-step explanation:

Hello There!

Heron's area formula is

$A=\frac{(a)(b)sin(c)}{2}$

all we have to do is plug in the values

$A=\frac{77*41sin79}{2} \\77*41=3157\\3157sin79=3098.997018\\\frac{3098.997018}{2} =1549.498509$

so the area of the triangle is 1549.498509

our final step is to round to the nearest hundredth

the answer would be 1549.5

Can someone help me write an equation in slope intercept form and then find the slope and Y intercepts for 3x-9y=27. (Only comme

GaryK [48]

The slope-intercept form:
$y=mx+b$
m - the slope
b - the y-intercept

$3x-9y=27 \ \ \ |-3x \\
-9y=-3x+27 \ \ \ |\div (-9) \\
\boxed{y=\frac{1}{3}x-3} \\ \\
\\ \hbox{the slope - } \boxed{m=\frac{1}{3}} \\
\hbox{the y-intercept - } \boxed{b=-3}$
