Question

A line passes through the origin and has a slope of 4. What is the equation of the line that is parallel to the first line and passes through the point (1,-2)?

A. y=4x+9
B. y=-4x+2
C. 4x-6
D. y=-1/4x-7/4 A line passes through the origin and has a slope of 4. What is the equation of the line that is parallel to the first line and passes through the point (1,-2)?

Answer 1

To get this we'll just use point-slope form of the line:

y-y1 = m(x-x1)

From the information given, m = 4, y1 = -2, x1 = 1

y + 2 = 4(x-1)
y+2 = 4x-4
y = 4x-6
