Question

hat is the equation of the line that is parallel to y = –4x + 3 and has a y-intercept of -1/3

Answer 1

What is the slope of the line that is parallel to the one they gave you?

Answer 2

What do you know about the slopes of lines that are parallel?

Answer 3

same slope

Answer 4

two paralell lines have same slope..okay..????so here slope =m=-4

now to find eq.is

y=-4x-1/3

Answer 5

That's right. Now use the point they gave you and the point-slope formula to write an equation. Can you do that?

Answer 6

Do you know the point-slope form of an equation?

Answer 7

i dont know the equation on the top of my head

Answer 8

oh I see they didn't give you a point, only the y intercept. That means that you need to use the slope-intercept form, not the point-slope form.

Answer 9

Slope intercept is y = mx + b where m is the slope which you know is the same as the line they gave you, and the y intercept is b. Using the slope of -4x and the y intercept of -1/3, can you write the equation?

Answer 10

y=-4 - 1/3
