Answer:
2x-y=4
Step-by-step explanation:
y=mx+b
b is the y-intercept which is -4
y=mx-4
find m(slope)
(2,0) and (0,-4)
(-4-0)/(0-2)
-4/-2=2 m=2
y=2x-4
add 4 to both sides
y+4=2x subtract y
4=2x-y
It says write in standard form which looks like this: 3x + 5y = 4
Answer: A) y= -1/2x+5
Step-by-step explanation: If the line is perpendicular to the original, the new "m" (coefficient of x) has to be the negative reciprocal of the original "m"
Since slope intercept is y=mx+b, you first want to get rid of the 2x by subtracting it from both sides. after, you should end up with 4y=16-2x or 4y=-2x+16, they both are the same, but some teachers might prefer the slope first. after that, you want to get the y alone, so you divide everything by 4. you should end up with the slope intercept form being y=-2/4x+4, simplified to y=-1/2x+4.
Answer:
(4, -1)
Step-by-step explanation:
(4, y) is a solution to x - 2y = 6.
Find the value of y:
The value of y is '-1'.
(4, -1) is a solution to the equation.
Hope this helps.
