Answer:
y=3x+5
Step-by-step explanation:
Point slope equation:
y=mx+b
m-slope, b- is y-intercept
equation given 2 points
y-y1 = m(x-x1)
For point (1,8) and slope m=(y2-y1)/(x2-x1) = 20-8/5-1=12/4=3
y-8 =3(x-1)
arange it in point slope format
y-8=3x-3
y=3x-3+8
y=3x+5
Answer:
no she is wrong
Step-by-step explanation:
7a-4+3a-6= 10a-10 therefore they are not equal
Answer:
Y~x
Y = k × v
Y = 22
Step-by-step explanation:
Y~ x
Y = k × X
Since the question isn't complete,we are going to assign figures to complete this very question and move on to other things and you can as well solve questions that are similar to this ones.
Now let's assume that the question says that is 6 when x is 3,what is y when x is 11.
To solve this question above,we need to find the constant of variation which will then enable us to know what y is when x is 11
Y~ x
Y = k × V
When y is 6 and x is 3,k will be
6 = 3k
K= 2
Now when k is 2,x is 11,y Will then be
Y = kx
Y = 2 × 11
Y = 22.
With this procedure,one can find any value of x or y when they have the constant of variation.
If you have a figure assigned to x and y is to be found,the constant of variation will help to get y and vice versa
