Eliminate p terms
times 2nd equation by -1
q-2p=-5
add to 2nd equation

q-2p=-5
7q+2p=29 +
8q+0p=24

8q=24
divide both sides by 8
q=3
sub back

2p-q=5
2p-3=5
add 3
2p=8
divide by 2
p=4

p=4
q=3

Which equation correctly uses point (–2, –6) to write the equation of this line in point-slope form? Y – 6 = y minus 6 equals St

GenaCL600 [577]

Answer:

Part 1) $y+6=\frac{2}{5}(x+2)$

Part 2) $y+6=\frac{5}{2}(x+2)$

Step-by-step explanation:

The equation of the line in point slope form is

$y-y1=m(x-x1)$

we're going to analyze two cases

First case

$Point\ (-2,-6)$

$slope\ m=\frac{2}{5}$

substitute

$y+6=\frac{2}{5}(x+2)$

therefore

y plus 6 equals StartFraction 2 Over 5 EndFraction left-parenthesis x plus 2 right parenthesis

Second case

$Point\ (-2,-6)$

$slope\ m=\frac{5}{2}$

substitute

$y+6=\frac{5}{2}(x+2)$

therefore

y plus 6 equals StartFraction 5 Over 2 EndFraction left-parenthesis x plus 2 right parenthesis

If you do what part B says for the first two equations in part A, it will answer part A.
Part C: You plug in coordinates on a table and see which points match and which points don't fit in the equations
