Find the slope of the line through the points (-13,15), (20,-7)

kifflom [539]

Answer:

$\boxed{ \bold{ \huge{\boxed{ \sf{ \frac{ - 2}{3} }}}}}$

Step-by-step explanation:

Let the points be A and B

A ( -13 , 15 ) ⇒( x₁ , y₁ )

B ( 20 , -7 )⇒( x₂ , y₂ )

<u>Finding</u><u> </u><u>the</u><u> </u><u>slope</u><u> </u> :

$\boxed{ \sf{slope = \frac{y2 - y1}{x2 - x1} }}$

plug the values

⇒ $\sf{slope = \frac{ - 7 - 15}{20 - ( - 13)} }$

We know that, $\sf{( - ) \times ( - ) = ( + )}$

⇒ $\sf{slope = \frac{ - 7 - 15}{20 + 13}}$

Calculate the sum

⇒ $\sf{slope = \frac{ - 22}{33} }$

Reduce the numbers with G.C.F 11

⇒ $\sf{slope = \frac{ - 2}{3} }$

Hope I helped !

Best regards!!

Which of the following is a solution of this equation?

ryzh [129]

Answer:

D. (-2,-3)

Step-by-step explanation:

substitute the point values of $x$ and $y$ into the equation $y=\frac{1}{2}x-2$

A. $0=\frac{1}{2}(5)-2$

$0=2.5-2$

$0$ ≠ $0.5$

B. $1=\frac{1}{2}(-1)-2$

$1=-.5-2$

$1$ ≠ $-2.5$

C. $-1=\frac{1}{2}(3)-2$

$-1=1.5-2$

$-1$ ≠ $-0.5$

D. $-3=\frac{1}{2}(-2)-2$

$-3=-1-2$

$-3=-3$
