3 (m) Slope: Slope y=mxtb y=mx tb

Sagot :

First, we need to calculate the slope

we need 2 points of the line

in this case, I will choose

P1(0,0)=(x1,y1)

P2(1,3)=(x2,y2)

the slope can be calculated with the next formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{3-0}{1-0}=\frac{3}{1}=3[/tex]

in order to calculate the equation we follow the next formula

[tex](y-y_1)=m(x-x_1)[/tex]

[tex](y-0)=3(x-0)[/tex]

the equation is

[tex]y=3x[/tex]
