Help me<br>please i need help​
soldier1979 [14.2K]

Answer:

5x - 2y = -2

Step-by-step explanation:

Slope: 5/2 and (-2,-4)

y-intercept= -4-(5/2)(-2) = 1

y = 5/2x+ 1

5/2x - y = - 1

2(5/2x - y) = -1*2

5x - 2y = - 2

Can someone please help me with#6-#8?I'm not sure how to find the answers and graph it in the graphs given.​
OLga [1]

Answers:

  • 6. Slope = -5/3; y intercept = 5
  • 7. Slope = -1; y intercept = 2
  • 8. Slope = 3; y intercept = 0

The graphs are below

========================================================

Explanation:

6)

Let's solve for y to get the equation in slope intercept form y = mx+b

5x+3y = 15\\\\3y = -5x+15\\\\y = \frac{-5x+15}{3}\\\\y = \frac{-5x}{3}+\frac{15}{3}\\\\y = -\frac{5}{3}x+5\\\\

That last equation matches with y = mx+b to get

m = -5/3 = slope

b = 5 = y intercept

To graph this, we plot the y intercept at (0,5). Then move down 5 and to the right 3 to arrive at (3,0) as the second point. This movement is directly tied to the slope. We only need two points to graph a straight line.

---------------------------------

7)

The equation y = -x+2, aka y = -1x+2, is already in slope intercept form

m = -1 = slope

b = 2 = y intercept

Start at (0,2) which is the location of the y intercept. Move down 1 and to the right 1 due to the slope -1/1 = -1. This should move us to the point (1,1). Connect the two points (0,2) and (1,1) with a straight line to finish up the graph.

---------------------------------

8)

We start with the origin (0,0) because the y intercept of y = 3x is 0. It might help to think of y = 3x as y = 3x+0

Then we move up 3 units and to the right 1 unit to get to (1,3) as our next point. Connect the two points with a straight line

slope = 3

y intercept = 0

Once again, the graphs are shown below.

kobusy [5.1K]

Answer:

x = 128

Step-by-step explanation:

x*(-8) = -16.     multiply both sides by -8 to get x by itself

x = 128
