1. A line goes through the points (1, 6) and (–2, 8). Write the equation of the line in Point-Slope form. Show your work algebraically for full credit.
2. A line goes through the points (1, 6) and (–2, 8). Write the equation of the line in Slope-intercept form. Show your work algebraically for full credit. Hint: this is the same line as in #1.
Answer:
1) [tex]y-6=-\frac{2}{3} (x-1)[/tex] and 2) [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]
Step-by-step explanation:
Ikr the bots are annoying.
Point-slope form is written as: [tex]y-y_1=m(x-x_1)[/tex]
Slope intercept form is written as: [tex]y=mx+b[/tex]
We also need to find the slope before putting it in this form, which can be done by [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
1) Points given are (1,6) and (-2,8)
Slope: [tex]m=\frac{8-6}{-2-1} =-\frac{2}{3}[/tex]
You can choose either of the two points to put into the formula. I just chose (1,6)
Answer: [tex]y-6=-\frac{2}{3} (x-1)[/tex]
2) Same points as before and we have the same slope as before. All we need is to find the y intercept which is our b in the equation. You can easily do this by plugging in a point and solving for b. I will choose point (1,6) again.
[tex]6=-\frac{2}{3} (1)+b[/tex]
[tex]6=-\frac{2}{3} +b[/tex]
[tex]6+\frac{2}{3}=-\frac{2}{3} +\frac{2}{3} +b[/tex]
[tex]b=6+\frac{2}{3}=\frac{20}{3}[/tex]
Answer: [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Answer:
The slope is 2.
Step-by-step explanation:
You can see on the intercepts that it goes rise 2 and run over 1 which would basically equal to 2.

Two numbers multiply to be -40 and add to be 3. What are the numbers?
Answer:
The numbers are (x,y)=(-5,8) or (8,-5)
Step-by-step explanation:
Let two numbers be x and y,
We have,
x+y=3
x=3-y---(i)
Now,
xy=-40
(3-y)y=-40 [From (i)]
3y-y^2=-40
y^2-3y-40=0
Factoring,
(y + 5) (y - 8)=0
Either,
y+5=0 or, y-8=0
y=-5 y=8
When y=-5,
x=3-y
3--5
3+5
8
When y=8,
x=3-y
3-8
-5
Find the Inverse function F(x)=4x-6
y = 4x - 6
x = 4y - 6; must solve for y in order to solve for inverse function
x + 6 = 4y
(x + 6)/4 = y
or
(x/4) + (6/4) = y
y = (x/4) + 3/2

the x-intercept was substituted incorrectly
write the correct equation
an equation of the parabola is y =__________
Answer:
Step-by-step explanation:
let the eq. of parabola be
y=ax²+bx+c
points (-1,0),(2,0),(3,4) and (0,-2) lie on it.
0=a-b+c
0=4a+2b+c
subtract
3a+3b=0
a=-b
4=9a+3b+c
-2=0+0+c
c=-2
a-b-2=0
-b-b-2=0
-2b-2=0
b+1=0
b=-1
a=-b=-(-1)=1
eq. of parabola is
y=x²-x-2

Maya drove 440 miles using 16 gallons of gas. At this rate, how many miles would she drive using 14 gallons of gas?
Thanks
385 miles
Step-by-step explanation:
440/16 = x/14
16x = 440 × 14
16x = 6,160
x = 6,160/16
x = 385 miles

y = -6
3.) -2(5)-5y = 30
-10-5y = 30
-5y = 40
y = -8

Find a, R, and T.
a = 4, R = 147, T = 33
Step-by-step explanation:
find a
a/(a + 7) = (16/3)/(44/3)
a/(a + 7) = 16/44
44a = 16a + 112
44a - 16a = 112
28a = 112
a = 112/28
a = 4
find R
2x + 5 = 3x - 9
5 + 9 = 3x - 2x
14 = x
m ∠R = 180° - (2x + 5)
= 180 - (2(14) + 5)
= 180 - (28 + 5)
= 180 - 33
= 147°
find T
m ∠T = 3x - 9
= 3(14) - 9
= 42 - 9
= 33°
