The first equation, 8x - 9y = - 23

Obtain the equation in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = ( $\frac{1}{2}$ , 3) and (x₂, y₂ ) = (- 4, - 1 )

m = $\frac{-1-3}{-4-1/2}$ = (- 4)/- $\frac{9}{2}$ = $\frac{8}{9}$

partial equation is y = $\frac{8}{9}$ x + c

to find c substitute either of the 2 points into the partial equation

using (- 4, - 1 ), then

- 1 = - $\frac{32}{9}$ + c ⇒ c = $\frac{23}{9}$

y = $\frac{8}{9}$ x + $\frac{23}{9}$ ← in slope- intercept form

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

rearrange the slope- intercept equation into this form

multiply through by 9

9y = 8x + 23 ( subtract 9y and 23 from both sides )

8x - 9y = - 23 in standard form

The function f(x) = x] is graphed over the interval [-6, 3]. Which translation of the graph has the domain (-3, 6]? 0 A. g(x) =

An interval graph in graphical theory is indeed an undirected graph formed by an interval set just on true line, with a top for every interval as well as an edge between vertex v to intersections. Graph intervals and these graphs are chordal graphs and graphs that are perfect, and the further discussion can be defined as follows:

Given:

$\bold{function\ f(x) = |x|}$
