Question

What’s the equation of the following

Answer 1

Step-by-step explanation

• Calculate the slope by using rise over run with given coordinate points.

`\bold {m = (rise)/(run) } \\ m = (0 - ( -2))/(0 - 10) \\ m = (0 + 2)/( - 10) \\ m = (2)/( - 10) \\ m = - (1)/(5)`

• From the slope-intercept form.

`y = mx + b \\ m = slope \\ b = y - intercept`

Because the graph passes origin point (0,0). Therefore the value of b is 0.

Answer

`\large \boxed {y = - (1)/(5) x}`
