Question

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

given slope.
through (-1, 1), slope = 4

Answer 1

y = 4x + 5

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 = 4 , then

y = 4x + c ← is the partial equation

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

1 = - 4 + c ⇒ c = 1 + 4 = 5

y = 4x + 5 ← equation of line
