Write the equation of the line y = mx + b with (7, 0) slope = -2

Answer 1

Using point-slope form

y - 0 = -2(x - 7)

Can you simplify and answer?

Answer 2

By using slope form and given information we should find y intercept which is b.

We plug-in y=0 , x=7, and m= -2 in slope form and

0=(-2)7+b =>> b=14,

Finally, we get y=-2x+14.
