2y+3x=90 what is x and y

1 answer:

4 0

If x=-6 then y=54.
If x=-4 then y=51.
If x=-2 then y=48.
If x=0 then y=45.
If x=2 then y=42.
If x=4 then y=39.
If x=6 then y=36.

There are an infinite variety of pairs of numbers for 'x' and 'y'
that can make that equation true.

You can use that equation to draw a line on a graph. Then
EVERY point on the line is a solution to the equation.

'x' and 'y' don't have single values unless you have TWO equations.

What is the slope of the line defined by the parametric equations x=-2+4t and y=1+4t ?

LekaFEV [45]

Answer:

The value of slope m = -1

Step-by-step explanation:

x = -2 + 4t

and y = 1 + 4t

Solving the both equations

x +2 = 4t

=> t = (x+2)/4 eq(1)

y-1 = 4t

=> t = (y-1)/4 eq(2)

Putting eq(1) = eq(2) as left hand side of both equations are same

(x+2)/4 = (y-1)/4

Cross multiplying

4(x+2) = 4(y-1)

4x + 8 = 4y -4

4x +4y = -4 -8

4x + 4y = -12

4(x+y) = -12

x+y = -12/4

x+y = -3

y = -x -3

The slope intercept form of line is:

y = mx + b

where m is the slope. Comparing with y = -x-3

The value of slope m = -1

Whats is y=1/3x+2 This is for math

marusya05 [52]

Answer:

an equation of a line

Step-by-step explanation:

This is an equation of a line. Lets walk through it.

y=1/3x+2

This is to find out what the Y coordinate would be when X is plugged in. So, if x was 6, you would take 1/3 of 6 to get 2, and add 2. The y intercept would be 4, since y=1/3(6)+2, y=2+2, y=4

Y=1/3x+2

This is what the slope is. If the slope is negative (ie. -3/4) the greater the x intercept the lower the y will be. (so if I had x=4 for a slope of -3/4, that would be y=-3/4(4)+2, y=-3+2, y=-1) But if the slope is positive (ie. 1/3) the greater the x value the greater the y value as well. (see graph attached below for positive)

Y=1/3x+2

This is the Y intercept. (This is NOT the y coordinate. This is only the coordinate of y if x=0) This number tells you where the Y intercept is. If it adds, the y intercept is positive. If it subtracts, the y intercept is negative.

Sorry if these explainations dont make sense. But, here is the graph for y=1/3x+2
