Question

PLEASE PLEASE HELP Write in standard form: a line that passes through (-1, 1) and has slope 2

Answer 1

Answer:

2x - y = - 3

Step-by-step 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 , then

y = 2x + c ← is the partial equation

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

1 = - 2 + c ⇒ c = 1 + 2 = 3

y = 2x + 3 ← in slope- intercept form

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

rearranging the slope- intercept form of the equation from above

2x + 3 = y ( subtract y from both sides )

2x - y + 3 = 0 ( subtract 3 from both sides )

2x - y = - 3 ← in standard form
