Answer:
y= 4x
Step-by-step explanation:
Slope-intercept form:
y=mx + b
Find the y-intercept (b).
8= 4(2) + b
8= 8 +b
8 - 8= 8 - 8 + b
0= b
Therefore, the equation of the line in slope-intercept form is:
y= 4x
Answer:
Step-by-step explanation:
x + 9 = -16
Subtract 9 form both sides
x + 9 - 9 = - 16 - 9
x = -25
Answer:
1
Step-by-step explanation:
a is greater than 0 and is inside the root of the equation
when a fraction is a power the bottom number of the fraction becomes the nth root and the top number becomes what the number is powered by
in this case the bottom number is 3 so the three goes on the place where the nth root goes
it is to the c power so c is on the outside
Answer:
A proportional relationship is something like:
y = k*x
Where k is the constant of proportionality
And a linear relationship is something like:
y = a*x + b
Is easy to see that if:
a = k, and b = 0, this would be a proportional relationship.
Then if we want to have a slope equal to 3, but this must not be a proportional relationship, we must only have b different than 0.
This could be something like:
y = 3*x + 1
The graph of this is:
