Question

Choose the equation that represents the line that passes through the point (?1, 6) and has a slope of ?3. question 2 options: y = ?3x 3 y = ?3x ? 6 y = 3x ? 3 y = 3x ? 1

Answer 1

y = 3x + 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 slope m = 3 , then

y = 3x + c ← is the partial equation

to find c substitute (1, 6 ) into the partial equation

6 = 3(1) + c = 3 + c ( subtract 3 from both sides )

3 = c

y = 3x + 3 ← equation of line
