Answer:

Slope = 4

Step-by-step explanation:

Use any two pairs from the table of values, say (0, 3) and (2, 11).

Slope = ∆y/∆x

Slope = $\frac{11 - 3}{2 - 0}$

Slope = $\frac{8}{2}$

Slope = 4

A. What iS the slope of the line that passes through (-2, 3) and (4, -5)?

Thepotemich [5.8K]

Answer:

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

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 2, 3 ) and (x₂, y₂ ) = (4, - 5 )

m = $\frac{-5-3}{4-(-2)}$ = $\frac{-8}{4+2}$ = $\frac{-8}{6}$ = - $\frac{4}{3}$

What expression is equivalent to m-4/m+4 divided by (m+2)

Ilya [14]

The first answer is correct coz ( for instance ) ‘x’ is divided by ‘y’ then this is similar to the x multiples by 1/y

So in that case, if we apply the same analogy to this question then the answer would be m-4/(m+4) ( m+2)

Suppose that $p$ and $q$ are positive numbers for which \[\log_9 p = \log_{12} q = \log_{16} (p + q).\] what is the value of $q/

SVEN [57.7K]

Given $p,q>0$ and $\log_9p=\log_{12}q=\log_{16}(p+q)=x$ (say).

Then,

$p=9^x\\ q=12^x\\ p+q=16^x$

From the above 3 equations,

$\frac{q}{p} =(\frac{12}{9} )^x\\ \frac{q}{p} =(\frac{4}{3} )^x\\ \frac{p+q}{p} =(\frac{16}{9} )^x\\ \frac{p+q}{p} =(\frac{4}{3} )^{2x}\\$

From the equations, we get

$\frac{p+q}{p}=(\frac{q}{p})^2\\ 1+\frac{q}{p}=(\frac{q}{p})^2\\ (\frac{q}{p})^2-\frac{q}{p}-1=0\\ \frac{q}{p}=\frac{1 \pm \sqrt{5}}{2}$

Since $p,q>0$ , the negative value is rejected.

$\frac{q}{p}=\frac{1 + \sqrt{5}}{2}$
