Given the point (-3, 6) and a line y=2x-8, write an equation of a line through the point and parallel to the line.
ch4aika [34]

Answer: y = 2x

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)

The equation of the given line is

y = 2x - 8

Comparing with the slope intercept form, slope = 2

If two lines are parallel, it means that they have the same slope. Therefore, the slope of the line passing through (- 3,-6) is 2

To determine the intercept, we would substitute m = 2, x = - 3 and

y = - 6 into y = mx + c. It becomes

- 6 = 2 × - 3 + c

- 6 = - 6 + c

c = - 6 + 6 = 0

The equation becomes

y = 2x

Please help me with math !!
Setler [38]

Answer:

  • a) x = 4
  • b) y = 1.25x + 15
  • c) (-12, 0)

Step-by-step explanation:

a) PQ is parallel to the y-axis and contains point (4, 5).

<u>It means its equation is:</u>

  • x = 4

b) RQ is parallel to OP.

Parallel lines have equal slopes.

<u>Find the slope of OP:</u>

  • m = 5/4 = 1.25

RQ has slope of 1.25 and passes through (- 8, 5).

<u>Find its equation using point-slope form:</u>

  • y - 5 = 1.25(x - (-8))
  • y - 5 = 1.25x + 10
  • y = 1.25x + 15

c) <u>The x-intercept is determined at y = 0:</u>

  • 0 = 1.25x + 15
  • 1.25x = - 15
  • x = - 15/1.15
  • x = - 12
