sammy [17]

Answer:

X= 2 Y=5

Step-by-step explanation:

Set them equal

-2x+9=4x-3 add -2x to both sides and -3 to both sides

12=6x then divide by 6

x=2

plug in 2 to either equation and solve for Y.

Y=-2(2)+9

Y=5

Which equation below represents a line with a slope of - 2/3 that passes through the point (-4.5 , 10)?

Lostsunrise [7]

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: $-4\frac{1}{2}$ . Substitute $-4\frac{1}{2}$ for x and 10 for y in the equation, then solve:
