What’s the equation of a line that passes through the point (1,24) and has a slope of -0.6?

Answer 1

The point-slope form of the equation of a line is:

y - y₁ = m(x-x₁)

where (x₁,y₁) is the point

and

m = slope

y - 24 = -0.6(x-1)

That is the equation of the line in point-slope form.

Now, if you want the equation in slope-intercept form,

y = -0.6x + 0.6 + 24

y = -0.6x + 24.6

Answer 2

y = mx + b

y = -0.6x + b

24 = -0.6(-1) + b

Now solve for b and update the 2nd line with the value for b
