Question

Write the equation of the line that is parallel to the line 3x - y = -3 and passes through the point (4, -2).

Answer 1

y = -one thirdx - 6

y = -one thirdx - 14

y = 3x - 6

y = 3x - 14

Answer 2

3x - y = -3
3x + 3 = y (rearrange)
y = 3x + 3
the slope of this line is 3
a parallel line will have the same slope

now we will use y = mx + b
slope(m) = 3
(4,-2)..x = 4 and y = -2
now we will sub and solve for b, the y intercept
y = mx + b
-2 = 3(4) + b
-2 = 12 + b
-2 - 12 = b
-14 = b

so our parallel equation is : y = 3x - 14

Answer 3

Thank you!!! Can you help me with another one?

Answer 4

sure thing :)

Answer 5

what ya got ?

Answer 6

Select the coordinates of two points that are on the line x = 5.


(5, 0) and (0, 5)

(5, 0) and (5, -2)

(5, 0) and (0, 2)

(0, 5) and (0, 2)
