The slope (m) of the line graphed is -4/2, because the line goes down 4 (-4) and over 2 (+2), which is change in y over change in x
m = -4/2 = -2
the y-intercept (b) of the line = -1, because the line crosses the vertical line at x=0 at y=-1
now for the equation:
y = mx + b
y = -2x + -1 = -2x - 1
f(x) = -2x-1
the last answer is correct
Answer:
or
or
Step by Step:
Step 1: Rewrite the equation (I used x instead of k.)
Step 2: Make x a loner by moving the 4 to the right side.
Step 3: Cancel multiplied terms on the left, multiply numbers on the right.
Step 4: Simplify.
Answer:
yes
Step-by-step explanation:
this is a function as there are no negative exponents/fractions as exponents/division in the function....this is in fact a binomial hope this helps!
Another name for CD would be DC it’s the same size and line just backwards
