Answer:
Table B represents a linear function.
Step-by-step explanation:
Table B is a linear function because y goes up by a constant, steady rate of 4 every time x goes up by one.
Answer:
When x = -1/4 and when x = -15/4
Step-by-step explanation:
The x intercept will be when f(x)=0, so
0 = 4|x+2| -7
7 = 4|x+2|
|x+2|=7/4 here you have to cases
case 1
x+2=7/4
x=7/4-2
x=-1/4 = -0.25
case 2
x+2 = -7/4
x = -2-7/4
x = -15/4 = -3.75
The slope would be 3/2. The formula is (y2-y1)/(x2-x1) which is (6-3)/(8-4)= 3/2
Answer:
y=1/2x + 10
Step-by-step explanation:
since the lines are parallel to each other they have the same gradient which is 1/2.
using the equation y-y1= m(x-x1) we can find the equation of the line
