Answer:
the system has a unique solution
Step-by-step explanation:
Start with an equation of a line in standard form,

Solve it for y to put it into the slope-intercept form:


The slope is -a/b.
Now look at your system of equations. The slope of the first equation is -a/b = -2/3. The slope of the second equation is -a/b = -6/5.
You have a system of two linear equations with two lines with different slopes, so the lines must intersect at a single point.
Answer: the system has a unique solution
Answer:
B
Step-by-step explanation:
Divide one sample of jumping jacks by each girl by their time to find the unit rate. Then compare unit rates. Recall, a unit rate is the number of jumping jacks done in one minute. Cortney does 15 jumping jacks in 1 minute in the first entry of the table. Mallory does 60 jumping jacks in 5 minutes according to a point on the graph. Divide 60/5=12. She does 12 jumping jacks per minute. Thus Cortney does 3 more per minute.
