Question

Daniel and Sofia both solve this system of equations:

y=−1.5x+5.7
y=-1.5x+5.7
y=0.5x+0.3
y=0.5x+0.3

Daniel's solution is
(1.1,2.4)
(1.1,2.4)
. Sofia's solution is
(2.7,1.65)
(2.7,1.65)
. They graph the equations to check their work.

Based on the graph, whose solution is more likely to be correct?

Answer 1

Answer:

Sofias solution is correct.

Step-by-step explanation:

First of all you do not need two sets of the same equation.

y=-1.5x + 5.7

y = 0.5x + 0.3

If you graph the y-intercepts first then graph the slope for the equation then you will get the right answer.

1) Graph 5.7 on the y-axis. | Then graph -1.5x going down on the y-axis and then go to the right on the x-axis.

Do the same for the other equation and you will get a solution of (2.7, 1.65) since they will intersect there.
