8 0

Answer:

Step-by-step explanation:

m = Y2 - Y1/ X2 - X1

m= -7 - 5/ 4 - 10

m = -12/ -6

m = 2

y - y1 = m ( x - x1)

y - 5 = 2 (x - 10)

What is the slope?

Lena [83]

Answer:

3/4

Step-by-step explanation:

We need two points to find the slope

( 20,20) and (60,50)

m = (y2-y1)/(x2-x1)

= (50-20)/(60-20)

= 30/40

= 3/4

What are the x-intercepts of y=x^2+2x-15

Sedbober [7]

Answer:

$(-5,0)$ and $(3,0)$

Step-by-step explanation:

Think about it.

What two numbers multiply to -15 and add up to 2?

The answers are 5 and -3.

So plug that into the factored form of a parabola.

$y=(x+5)(x-3)$

To find the x-intercepts, plug in 0 for $y$ .

$(x+5)(x-3)=0$

Since we are multiplying, at least one of the terms has to equal 0.

$x+5=0 \\ x-3=0 \\ \\ x=-5,3$

So the x-intercepts are $(-5,0)$ and $(3,0)$ .
