Question

The slope of a line is –2 and its y-intercept is (0, 3). What is the equation of the line that is parallel to the first line and passes through (2, 2)?

Answer 1

use this formula: \(y-y_1=m(x-x_1)\)

parallel lines have same slope, so second line will have slope of -2

for point, plug in 2 for x1 and 2 for y1

Answer 2

is this clear?

Answer 3

yeah

Answer 4

ok, so after plug in, simplify it to y=mx+b. what did you get?

Answer 5

y=-2x+6

Answer 6

right! good job :)

Answer 7

thanks
