Question

if the slope of a line is 12 and the line goes through the point (3,36), express the equation of this line in slope-intercept form.

Answer 1

Use the point-slope form for the equation of a line:

 

y - y₁ = m(x - x₁)

 

where:

• (x₁,y₁) is a known point on the line = (3,36)
• m is the line's slope = 12

 

y - 36 = 12(x - 3)

 

Now convert it to the slope-intercept form, y = mx + b:

 

y - 36 = 12x - 36

Add 36 to both sides

y = 12x
