PLEASE HELP
Write the equation that describes
each line in the slope-intercept
form.
1. slope = 3, y-intercept = -2

2. slope = 0, y-intercept = 1/2

3. slope = 3/2 ,(2, 7) is on the

4. What is the slope of the line containing the ordered pair (2,3) and (-4,0)

5. is the equation 2x+8= ya direct variation (yes or no)

6. The equation 2x+5y=0 is a direct variation what is the constant variation

7. if the value of y varies directly with x, and y=4 when x=-10 find when x= 35

SOLVE EACH EQUATION FOR Y

8. 4x+2y=10

9. 3x+2=6y

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!

The heir to the austrian throne, archduke franz ferdinand was gunned down by a young serbian terrorist. germany urged austria to declare war on serbia. russia mobilized against austria, then germany mobilized against russia. france and britain mobilized against germany. then young men such as adolf hitler volunteered in the war.
