The point-slope form:
We have the points (3, -4) and (5, 1). Substitute:
The standard form:
<em>multiply both sides by 2</em>
<em>use distributive property</em>
<em>subtract 2y from both sides</em>
<em>subtract 15 from both sides</em>
<h3>Answer: 5x - 2y = -7</h3>

Answer: maybe line C, i dont know
Step-by-step explanation:
x = -2
y = 1
let's multiply second equation by 4 to get a common coefficient of y variable.
16x-8y=-40
add the equations
3×+8y=2
16x-8y=-40
----------------
3x+16x = -38
19x = -38
x = -2
substitute x
3×-2 + 8y = 2
-6 + 8y = 2
8y = 2+6
y = 1
check the answer
-6+8 = 2
-8-2= -20
