Choose the equation that has solutions (5,7) and (8,13).

Alekssandra [29.7K]

<h2>Answer:y=2x-3</h2>

Step-by-step explanation:

$(x_{1},y_{1})$ is called solution of a equation if $(x_{1},y_{1})$ satisfies the equation.

Consider the equation $y=2x-3$ ,

For point $(5,7)$ ,

$LHS=y=7$

$RHS=2x-3=2(5)-3=10-3=7$

So, $RHS=LHS$

The point $(5,7)$ satisfies the equation.

For point $(8,13)$ ,

$LHS=y=13$

$RHS=2x-3=2(8)-3=16-3=13$

So, $RHS=LHS$

The point $(8,13)$ satisfies the equation.

So,both the points satisfy the equation $y=2x-3$

Find the distance between the points (7, -2) and (2, -10).

katrin2010 [14]

Answer:

$\sqrt{89}$

Step-by-step explanation:

d = $\sqrt{(x_{1}-x_{2} )^{2} +(y_{1} -y_{2} )^{2} }$

d = $\sqrt{(7-2)^{2} +(-2+10)^{2} }$

d = $\sqrt{5^{2} +(-8)^{2} }$

d = $\sqrt{25+64}$

d = $\sqrt{89}$
