Question

Write the slope-intercept of the equation of the line through the given point with the given slope.

through: (-1,-5), slope=2

Answer 1

y = 2x - 3

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , thus

y = 2x + c ← is the partial equation

To find c substitute (- 1, - 5) into the partial equation

- 5 = - 2 + c ⇒ c = - 5 + 2 = - 3

y = 2x - 3 ← equation of line

Answer 2

-5 = 2(-1) + b

Explanation:

the slope-intercept form is writing as y = mx +b
