Answer: y=9x + 26

Step-by-step explanation:

Notice that for two lines to be parallel they must have the same slopes but different y intercept.

So the equation y =9x + 2 has a slope of 9 and y-intercept of 2  so using the points  we can determine  the y intercept of the line parallel to it to find the.

Using the slope intercept form formula which is y = mx + b  we can plot in the slope and the given coordinates to solve for b.

The coordinate is (-2,8)  which the y value is 8 and the x value is -2

so  8 = 9(-2) +b    solve for b

  8 = -18  + b

 +18   +18

b = 26  

The y intercept is 26  so the equation will be y=9x + 26

It’s a positive slope, constant slope, and increasing function. Because it’s a straight line going diagonally to the top right, you know the slope is positive, constant, and the function is positive.

What is the equation of the line perpendicular to y=1/2x+6 that passes through the point (4, 1)?
Oksana_A [137]

Answer:

A

Step-by-step explanation:

Find the slope of the perpendicular line.

The slopes are related by the formula

m1 * m2 = - 1

Since m1 is 1/2, m2 must be -2

So far what you have is y = -2x + b

Find the y intercept (b).

The new line goes through (4,1)

x = 4

y = 1

1 = -2(4) + b

1 = - 8 + b  

b = 1 + 8

b = 9

The answer is

y = - 2x + 9

The sum of two numbers is 41. The larger number is 17 more than the smaller number. What are the numbers?
postnew [5]
Let x = the larger number
Let x - 17 = the smaller number
x + x + 17 = 41
2x + 17 = 41
2x = 58
x = 29
x - 17 = 29 - 17 = 12
