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.
