#1
the answer would be C.) y = -2x + 4
here is why:
start with y = mx +b
imput the slope and the coordinates:
-8 = -2 x (6) + b
then solve for b
-8 = -2 x (6) + b
-8 = -12 + b
b = 4
so then the equation would be
y = -2x + 4
#2
y - 3 = 2 ( x - 7)
y - 3 = 2x - 14
y = 2x - 11
because none of the answers are in standard y=mx+b form I would say that the answer would be none.
Answer:
Variable "m"
Step-by-step explanation:
Hello!
The equation
is perhaps the most used equation when representing a line. The parts of the equation:
- y = output, y-value, ordinate...
- m = slope, rate of growth, rise over run...
- x = input, x-value, abscissa...
- b = y-intercept
____________________________________________
Let's use an example: y = 2x + 5
We want to find the y-value when x is 2.
To solve, simply plug in 2 for x:
- y = 2(2) + 5
- y = 4 + 5
- y = 9
So, the coordinate when x is 2 is (2,9), remember that coordinates are written in (x,y) format.
Image: y = 2x + 5
Do 28+2 which is 30, and then 30/10 which is 3, so 3 equals z
Answer:
Which graph represents the solution set to this system of equations? –x + 2y = 6 and 4x + y = 3
On a coordinate plane, a line goes through (negative 1, negative 1) and (0, 3) and another line goes through (1, 4) and (2, 2).
On a coordinate plane, a line goes through (negative 4, 0) and (0, 4) and another line goes through (negative 1, 1) and (0, negative 3).
