Question

Write an equation for line l in point-slope form and slope-intercept form.

A) y - y₁ = m(x - x₁); y = mx + b
B) y = mx + b; y - y₁ = m(x - x₁)
C) y = mx + b; y + y₁ = m(x + x₁)
D) y - y₁ = m(x - x₁); y - mx = b

Answer 1

The equation for line l in point-slope form is y - y₁ = m(x - x₁), and in slope-intercept form it is y = mx + b. The correct option is A) y - y₁ = m(x - x₁); y = mx + b.

Step-by-step explanation:

The equation for a line in point-slope form is y - y₁ = m(x - x₁), and the equation in slope-intercept form is y = mx + b. The correct option is A) y - y₁ = m(x - x₁); y = mx + b.

In the point-slope form, m represents the slope of the line, while (x₁, y₁) represents a point on the line. In the slope-intercept form, m represents the slope, and b represents the y-intercept.
