Find the slope of the line through p and q. p(1, −9), q(−3, 2)

1 answer:

7 0

To find the slope,we can use the point-slope form:
$y1 - y2 = m(x1 - x2)$
Where m is the slope.

In this case,the equation would be:
-9-2 = m(1-(-3))
-11 = m(1+3)
-11 = 4m
m = -11/4

Therefore the slope is -11/4.

Hope it helps!

Answer:

G. $\frac{3.2}{2} = \frac{a}{8}$

Step-by-step explanation:

Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.

Thus:

$\frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b}$

Therefore, the proportion that must be true is:

✔️ $\frac{3.2}{2} = \frac{a}{8}$

Solve the system of equations:<br> y = x + 2<br> y = x2 + 5x + 6<br> HELP PLZ

soldier1979 [14.2K]

Answer:

x=2(twice)

y=0(twice)

Step-by-step explanation:

This question can be solved using substitution method

So let's solve

y=x+2....(1)

y=x2+5x+6....(2)

Substitute (1) into(2)

X+2=x2+5x+6

Collect like terms

X2+5x-x+6-2=0

X2+4x+4=0

X2+2x+2x+4=0

X(x+2)+2(x+2)=0

(X+2)(x+2)=0

X+2=0

Substrate 2 from both sides

X=-2

X+2=0

X=-2

Let's substitute the value of x into (1)

y=x+2

y=-2+2

Y=0(twice)
