Answer:

$\frac{7}{5}$

Step-by-step explanation:

Slope between two points:

$Slope=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$(x_{1},y_{1} )=(-8,-3), (x_{2},y_{2} )=(-3,4)$

$m=\frac{4-(-3)}{-3-(-8)}$

Refine.

$m=\frac{7}{5}$

Which graph shows a set of ordered pairs that represents a function?

pychu [463]

Answer:

B represents a function.

Step-by-step explanation:

Recall these characteristics of a "function:"

Only one y-value can be associated with each x-value.

Thus, A could not represent a function because there are two points with x = 1 and two different y-values: (1, 1) and (1, -2).

B represents a function because for each input (x-value) there is one and only one y-value associated.

C not a function: (2, 3) and (2, -3) have two different y-values associated with one x-value (2).

D not a function: (-3, 4) and (-3, -4) (see A and C, above)

Which statement BEST explains the relationship between lines GF & HJ?

Pavel [41]

Answer:

Option (4)

Step-by-step explanation:

Slope a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

m = $\frac{y_2-y_1}{x_2-x_1}$

Since, blue line is passing through two points (-4, -2) and (0, 4),

Slope of the blue line = $\frac{4+2}{0+4}$

= $\frac{3}{2}$

Similarly, green line is passing through two points (-4, 1) and (0, -2),

Slope of the green line = $\frac{1+2}{-4-0}$

= $-\frac{3}{4}$

Since, $\frac{3}{2}\neq -\frac{3}{4}$

Neither these slopes are opposite reciprocals.

Therefore, both the lines are neither parallel nor perpendicular.

Option (4) will be the correct option.

Zolol [24]

Hello :
y= <span>√(x+6) +2
answer :
</span><span>d.(-2,4)
because : when x =-2 y =</span>√(-2+6) +2 = √4 +2 2+2 = 4
