Find the equation of a line parallel to y - 5 = 6x - 10 that passes through the point (4, 10). (answer in slope-intercept form)
UNO [17]
Our equation is y = 6x - 5 when simplified. In order to be parallel, the equation for the answer must also have a slope of 6x. This rules out options C and D.

Now just plug in 4 for the x-value for each one to get your answer. A little mental math and I can already tell you it's option A.

6(4) - 14 = y
24 - 14 = y
10 = y

10 = 10

Whereas for option B:

6(4) + 14 = y
24 + 14 = y
38 = y

38 ≠ 10

Option A is your answer.

If an=5n-3 find the common difference​
Hitman42 [59]

Answer:

d = 5

Step-by-step explanation:

The common difference d of an arithmetic sequence is

d = a₂ - a₁ = a₃ - a₂ = a_{n} - a_{n-1}

Given

a_{n} = 5n - 3

Generate the first 2 terms of the sequence by substituting n = 1, n = 2

a₁ = 5(1) - 3 = 5 - 3 = 2

a₂ = 5(2) - 3 = 10 - 3 = 7

d = 7 - 2 = 5

Solve the system of equations by graphing.<br> y=−3x−4 y=x+4
Bumek [7]
I hope this helps: first when graphing y=Mx+b always start with ur y-intercept or b so in this case y = -3x + -4 u would go down 4 spaces and right three spaces or till u reach -3 on the second quadrant. For the second one you’ll do (0,0) find the slope with the coordinate given to you.
