Question

Choose the equation below that represents the line passing through the point (2, -4) with a slope of 1/2 .

y =1/2 x + 5

y =1/2 x - 3

y = 1/2x - 5

y = 1/2x + 3

Answer 1

plug in x = 2 and y = -4 into each equation and find out which one is satisfied

Answer 2

hint - the correct option will contain a minus sign ( as y = -4)

Answer 3

so you only need to check 2nd and 3rd equations

Answer 4

oh ok thank you

Answer 5

Could You Help Me With This One . . . Choose the equation of the line passing through the point (-2, 4) and perpendicular to y = -x + 4.

Answer 6

y - 5 = (x + 1)

y + 1 = (x - 5)

y + 5 = -(x - 1)

y - 1 = (x + 5)

Answer 7

y = -x + 4
- what is the slope of this line?

Answer 8

the slope of the following line is m:

y = mx + b

- the number in front of the x indicates the slope

y = -x - 4
can be written y = -1x - 4
so whats the slope?

Answer 9

y = -1/2x + 4

Answer 10

no the slope of y = -1x - 4 is -1
- right?

Answer 11

no i was finishing the question . . . Choose the equation of the line passing through the point (-2, 4) and perpendicular to y = -1/2x + 4.
