Answer:
Step-by-step explanation:
To find y=mx+b we need to identify two points. I picked (20,45) and (50,65)
From these two points we can find the slope, m.
m=(y2-y1)/(x2-x1)
m=(65-45)/(50-20)
m=20/30=2/3 so now our line is
y=2x/3+b, we can solve for b using either point, I’ll use (20,45)
45=2(20)/3+b
45=40/3+b
b=45-40/3
b=(135-40)/3
b=95/3 so the line is
y=(2x+95)/3
Answer:
See explanation. (Also you can write an equation several different ways so without the choices I cannot tell you which)
Step-by-step explanation:
Slope-intercept form is y=mx+b
So one way to write the equation is y=-3/4 x +3/2
There are more ways to write it.
Every line about to write is a way to write it.
Multiply both sides by 4: 4y=-3x+6
Add 3x on both sides: 3x+4y=6
Subtract 6 on both sides: 3x+4y-6=0
There are a lot of ways to write an equation like this.

Hope this is right! :) please help on my recent question on history, you get BRAINLYIST AWNSER and 10 points if you answer :/
Okay, so one of the geometric theorems is that two of the inside angles equals the outside angle in a situation like this one.
So, set them equal:
2x+ 2 + 4x + 8 = 8x - 30
Combine like terms:
6x + 10 = 8x - 30
40 = 2x
x = 20
