Answer:
x =
y =
Step-by-step explanation:
2x = 10y - 8
3x + 4y + 5 = 0
2x = 10y - 8
x = 5y - 4
3x + 4y + 5 = 0
3 ( 5y - 4 ) + 4y + 5 = 0
19y - 7 = 0
19y = 7
y =
x = 5y - 4
x = 5 ( ) - 4
x =

Answer:
Option C
Step-by-step explanation:
If a line passes through a point, then that point is called a solution to the line's equation. Substituting the x and y values of that solution into the equation will give a true statement. So, to find out which option is correct, we can substitute the x and y values of (-4.5, 10) into each equation and see if the result is a true statement.
Let's try this with option C. To make things easier, convert -4.5 into decimal form: . Substitute
for x and 10 for y in the equation, then solve:
10 does equal 10, so this is a true statement. Option C is the right answer.
