Answer:
The slope is m=7
Step-by-step explanation:
The Slope of a Line
Suppose we have a line that passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given the points (3,5) and (4,12), thus: x1=3, y1=5, x2=4, y2=12. Substituting:
[tex]\displaystyle m=\frac{12-5}{4-3}=\frac{7}{1}=7[/tex]
The slope is m=7
