Answer: C. y=1/3x+3
Step-by-step explanation:
The line hits the y axis at 3 so 3 is the y intercept and the line rises one accross 3 so 1/3 is your slope. Together its y=1/3x+3
Answer:
65 in²
Step-by-step explanation:
1. Break up the figure (We'll do it left to right): We now have 3 rectangles:
<em>(6 - 4) x 4, (4 + 8) x 4, and 3 x 3</em>
2. Find the two lengths: 6 - 4 = <em>2</em>, 4 + 8 = <em>12</em>
3. Find the three areas: 2 * 4 = <em>8</em>, 12 * 4 = <em>48</em>, 3 * 3 = <em>9</em>
4. Add the areas: 8 + 48 + 9 = 65 in²
Answer:
A) x=40
Step-by-step explanation:
As 1 cm= 5 km
then, 8 cm= 5*8= 40
Answer:
m=-3/4
Step-by-step explanation:
First locate two points that are on solid intersections, (-3, 2) and (1, -1).
<u>y2</u><u>-</u><u>y1</u>
Then use x2-x1' where -1 is y2, 2 is y1, 1 is x2, and -3 is x1.
Plug in numbers, <u>-1-2</u><u> </u>= <u>-</u><u>3</u>
1+3 = 4
-3/4 is m (Slope).
