Question

Find the equation of the line that passes through the point (-1, 2) and that has a
slope of 4.
Oy=2x-1
Oy=-1*+6
Oy= 4x+6
Oy=12-1

Answer 1

Answer:

y = 4x + 6

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 = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 1, 2) into the partial equation

2 = - 4 + c ⇒ c = 2 + 4 = 6

y = 4x + 6 ← equation of line
