Write an equation of a line in a slope-intercept form that passes through (-2,1) with a slope of 5.
KonstantinChe [14]
If they give you a point and slope, use point slope form.
Then simplify to get slope intercept form (y = mx + b)
slope (m) = 5
(-2, 1)

y - y1 = m(x - x1)
y - 1 = 5(x + 2)
y - 1 = 5x + 10

y = 5x + 11

valina [46]

Answer:

-2

Step-by-step explanation:

Start with the vertex form of the equation of a parabola:  y - k = a(x - h)^2

Here h = -2, k = -3, x = -1, y = -5.  Find a:

-5 - [-3] = a(-1 - [-2])^2, or

-5 + 3 = a(1)^2, or

-2 = a

The unknown coefficient is -2.

Fill in the gaps in the arithmetic sequence -3, _ ,_ , _, _, _ 12
lord [1]

Answer:

  -0.5, 2, 4.5, 7, 9.5

Step-by-step explanation:

The given terms are 6 apart, so the common difference is 1/6 of their difference:

  d = (12 -(-3))/6 = 15/6 = 5/2 = 2.5

Add 2.5 to each term to get the next one. Then the sequence is ...

  -3, <u>-0.5</u>, <u>2.0</u>, <u>4.5</u>, <u>7.0</u>, <u>9.5</u>, 12
