Find the equation lines (4, 5)(7, 3)

mash [69]

Step-by-step explanation:

Hey there!

The equation of a st.line passing through points (4,5) and (7,3) is;

$(y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)$

Put all values.

$(y - 5) = \frac{3 - 5}{7 - 4} (x - 4)$

Simplify it.

$(y - 5) = \frac{ - 2}{3} (x - 4)$

$3(y - 5) = - 2x + 8$

$3y - 15 = - 2x + 8$

$2x + 3y - 23 = 0$

Therefore therequired equation is 2x+3y-23=0.

Hope it helps..

What additional information is needed to prove that the triangles are congruent using the AAS congruence theorem? LO ≅ LM OA ≅ M

geniusboy [140]

Answer:

∠LOA≅∠LMA

Step-by-step explanation:

The first two options are incorrect because you need one more set of congruent ANGLES, not SIDES. The last option would prove congruency, but through ASA, not AAS. So it would be the third option.
