Question

Lines d, e, and f are parallel. That means they have the same slope. Each of these lines has a slope of -3. Enter numbers to complete an equation fir each line

Answer 1

Line d y = -3x -3

Line e y = -3x -1

Line f y= -3x+2

Explanation:

To write the equation of a line, you need the slope and the y-intercept. The slope of each line is -3. Find the y-intercept on the graph and then substitute it into the equation y = mx+b for b.

Line d has y-intercept (0,-3)

y = -3x -3

Line e has y-intercept (0,-1)

y = -3x -1

Line f has y-intercept (0,2)

y= -3x+2
