Answer:
y = 2x - 5
Step-by-step explanation:
Using the slope intercept formula y2 - y1 / x2 -x1...
You get a slope of 2 so y = 2x +b
Then to find b the intercept, you plug in one of the coordinates like so...
1 = 2(3) + b
Then solve to get an intercept of -5.
So the slope-intercept form would be...
y = 2x - 5
y=6x-3
put a point on (0,-3) this is your y intercept
go up 6 and over 1 this should land you at (1,0) do this again and your at (2,6)
go back to the y intercept now go down 6 and over 1, this should land you (-1,-6)
continue to do this until you graph is filled
A Domain is the lowest and highest x value (-5,-2) is how it is formatted this means -5 to -2
Range is the lowest to highest Y value so (-3,3)
(-5,-2) - domain
(-3,3) - range
B Intercept are when the line crosses the acis labeled x so
(-2,0) and (2,0)
C F(1) means what is x when y is equal to 1 so we must estimate this
(-1,1) and (1.5,1)
D f(x) = -3 is when y is -3 so we look at the graph to see
-5 and 4 are the values for x
E f(x) < 0 means when y is above the x axis
This is between the x values of -2 and 2 or (-2,2)
Multiply 2/3 by 8 and you will get 16/3 or 5.33 repeating.
Answer:
Step-by-step explanation:
-x - 6 > 21 - 28x
27x - 6 > 21
27x > 27
x > 1
