Answer:

Step-by-step explanation:

The functions are written in slope-intercept form.

The graph crosses the y-axis at (0,-2), so the y-intercept is -2.

You can eliminate D because its y-intercept is +2, not -2.

(1,1) and (0,-2) are points on the line.

The slope of the line is (-2-1)/(0-1) = 3

You can eliminate B because its slope is ⅓.

Eliminate C because its slope is -3, not 3.

Answer B

HELP!!!!

OverLord2011 [107]

Answer:

Step-by-step explanation:

You just need the distance formula here. It's very simple to follow:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

which, for us, looks like this:

$d=\sqrt{(13-4)^2+(19-7)^2}$ and

$d=\sqrt{9^2+12^2}$ and

$d=\sqrt{81+144}$ and

$d=\sqrt{225}$ so

d = 15

What is 2/3 + 1/4<br>*please help*

Tcecarenko [31]

$\frac{2}{3}+\frac{1}{4}$

Re-write with a common denominator, in this case 12:

$\frac{2 \times 4}{3 \times 4}+\frac{1 \times 3}{4 \times 3}$
$\frac{8}{12}+\frac{3}{12}$

Add:
$\frac{8}{12}+\frac{3}{12} = \frac{11}{12}$
