olga2289 [7]

Answer:

a=3

Step-by-step explanation:

x – 2y = 4

ax– 6y = 12

To have infinitely many solutions, the two equations have to be equal

Multiply the first equation by 3

What is the slope of the line in the graph?<br>4th possible answer is 4/3<br>----<br>بنام<br>​
Delvig [45]

Answer: Second option.

Step-by-step explanation:

The slope of a line can be calculated with this formula:

 m=\frac{y_2-y_1}{x_2-x_1}

Then, you need to choose two points of the line shown in the graph and substitute them into the formula for calculate the slope:

Let's pick the points (-4,4) and (4,-2).

Substituting:

m=\frac{-2-4}{4-(-4)}

Simplifiying,  you get that the slope of the line in the graph is:

m=\frac{-2-4}{4-(-4)}\\\\m=\frac{-6}{4+4}\\\\m=\frac{-6}{8}\\\\m=-\frac{3}{4}
