Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
+ = 1 ( multiply through by 2 to clear the fractions )
x + y = 2 ( subtract x from both sides )
y = - x + 2 ← in slope- intercept form
(a) with slope m = - 1
(b) with y- intercept c = 2
(c)
Parallel lines have equal slopes, thus
y = - x + c ← is the partial equation of PQ
To find c substitute (2, - 8) into the partial equation
- 8 = - 2 + c ⇒ c = - 8 + 2 = - 6
y = - x - 6 ← equation of PQ
To show (- 1, - 5) lies on PQ, substitute x = - 1 into the equation and evaluate for y.
y = - (- 1) - 6 = 1 - 6 = - 5 ← the given y- coordinate
Thus PQ passes through (- 1, - 5 )
Y would be the output value after inputting an X value and solving the necessary equation.
On the pictured graph, the numbers along the bottom are the X values and the numbers along the side are the Y values.
Looking at where the yellow dots are located on the X axis, there ia a dot at 0, 7, 14, 21, 28 and 35.
Now look at the corresponding Y values for each of those dots, they are at 0, 42, 84, 126, 168 and 210.
To find the proportionality of the graph using the equation y =kx, we can fill in the Y and X values and solve for k.
using x = 7 and Y = 42, the equation becomes 42 =k(7).
To solve for k divide both sides by 7: k = 42/7 = 6
When you replace the x and Y with the other numbers on the graph k is also equal to 6, so the correct equation would be B. y = 6x
I believe that that is an irrational number. It appears to go on without ending and without repeating.
