Write the set of points from -6 to 0 but excluding -4 and 0 as a union of intervals
First we take the interval -6 to 0. In that -4 and 0 are excluded.
So we split the interval -6 to 0.
Start with -6 and go up to -4. -4 is excluded so we break at -4. Also we use parenthesis for -4.
Interval becomes [-6,-4) . It says -6 included but -4 excluded.
Next interval starts at -4 and ends at 0. -4 and 0 are excluded so we use parenthesis not square brackets
(-4,0)
Now we take union of both intervals
[-6,-4) U (-4,0) --- Interval from -6 to 0 but excluding -4 and 0
Hello!
So the equation that you want to use is
y = mx + b
Now you can plug in both the slope and your points to find b.
3 = -1/2(2) + b
3 = -1 + b
4 = b
So now that we've found b, we can use the original equation and only plug in the slope and b
y = -1/2x + 4
So to find the y-intercept, we need to plug in 0 for x
y = -1/2(0) + 4
y = 0 + 4
y = 4
Your y-intercept is (0,4)
Hope this helps!
The answer to this is 8 1/2.
The correct answer would be d (2,-5)
