Determine if the lines are parallel, perpendicular, neither or the same line: y = -2x + 1 and 2x + y = 5.

Step-by-step explanation:

They are parallel.

Parallel lines have the same slope.

for the line y = -2x + 1 the slope is -2 and when we put the line 2x + y = 5 in general equation it will be y = -2x + 5, and it's slope is also -2.

Therefore, the lines are parallel

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
