Answer:
Lorena made a mistake when she subtracted x1 from x2
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
In this problem we have
[tex]=\frac{63-51}{-2-(-4)}[/tex]
[tex]=\frac{12}{-2+4}[/tex]
[tex]=\frac{12}{2}[/tex]
[tex]=6[/tex]
The points are [tex](-4,51)[/tex] and [tex](-2,63)[/tex]
therefore
Lorena made a mistake when she subtracted x1 from x2
