Answer:
b) y = f(x - 7) - 3
Step-by-step explanation:
it adds if its goes to the right and subtracts if it goes to the left
And when it goes down then it will also decrease in number.
that is why b) y = f(x - 7) - 3 is the correct answer to put
well for a line, to get its slope all we need is two points, so let's use (-6, 5) and (0, 1), and get the equation of it.
now, where's the y-intercept of that line? well, to get the y-intercept, we set x = 0 and solve for "y"....hmmmm wait a second, notice (0, 1), x = 0, y = 1, that's the y-intercept already.
- Midpoint Formula:
Given our two points, (-3,9) and (-1,4), we can apply them to the midpoint formula and solve for it as such:
<u>Your midpoint is (-2,6.5)</u>
Answer:
(x, y ) = (3, 14 )
Step-by-step explanation:
since both equations express y in terms of x, equate the right sides
7x - 7 = 6x - 4 ( subtract 6x from both sides )
x - 7 = - 4 ( add 7 to both sides )
x = 3
substitute x = 3 into either of the 2 equations for y
using y = 6x - 4 = (6 × 3 ) - 4 = 18 - 4 = 14
solution is (3, 14 )
