What is the solution to the system of equations below when graphed y= -2x +3, y= -4x + 15

Step-by-step explanation:

These are linear functions. The graph is a straight line. We only need two points to draw a graph.

We choose any two values of x, substitute and calculate the value of y.

For y = -2x + 3

x = 0 → y =-2(0) + 3 = 0 + 3 = 3 → (0, 3)

x = 1 → y = -2(1) + 3 = - 2 + 3 = 1 → (1, 1)

For y = -4x + 15

x = 3 → y = -4(3) + 15 = -12 + 15 = 3 → (3, 3)

x = 4 → y = -4(4) + 15 = -16 + 15 = -1 → (4, -1)

Look at the picture.

The solution is the coordinates of the point of intersection of lines.

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
