Answer:
• Slope=3
,
• Equation: y=3x
Explanation:
The given line passes through points (1,3) and (0,0).
[tex]\begin{gathered} \text{Slope}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}} \\ =\frac{3-0}{1-0} \\ =\frac{3}{1} \\ m=3 \end{gathered}[/tex]
The equation of a line is given in the form:
[tex]\begin{gathered} y=mx+b \\ m=\text{slope} \\ \text{b}=y-\text{intercept} \end{gathered}[/tex]
The line crosses the y-axis at y=0, therefore:
• y-intercept, b=0
The equation of the line is:
[tex]\begin{gathered} y=mx+b \\ y=3x+0 \\ y=3x \end{gathered}[/tex]
