Answer:

  • (3, 1.5)

Step-by-step explanation:

<u>Given the system: </u>

  • 6x + 8y = 30
  • y=1/2x

<u>Substitute y and solve for x:</u>

  • 6x + 8y = 30
  • 6x + 8(1/2x) = 30
  • 6x + 4x = 30
  • 10x = 30
  • x = 3

<u>Find y:</u>

  • y = 1/2x
  • y = 1/2(3)
  • y = 1.5

Solution is (3, 1.5)

What is the slope of the line through (-9.6) and (-6,-9)?
lisov135 [29]

Answer:

Slope= -5

Step-by-step explanation:

The formula for slope= (y2-y1)/(x2-x1)

First you label your points:

X1=-9

Y1=6

X2=-6

Y2=-9

Next you plug in your points and solve

-6-9=-15

-6-(-9)=3

And finally, you simplify

Slope= -15/3=5

As you may have noticed the formula for gradient is

(Change in <span>yy</span>)/(change in <span>xx</span>)

Therefore

<span><span>(−5−15)/(−8−−2)</span><span>(−5−15)/(−8−−2)</span></span>

<span><span>=−20/−6</span><span>=−20/−6</span></span>

<span><span>=10/3</span></span>
