Given the equation y-5=5x, determine whether the points (2,12) and (-2, -5) are a solution on the graph. SHOW ALL WORK

Try this option:
to define just substitute the coordinates into the equation of the line.
For point (2;12), it means x=2; y=12:
12-5=5*2 ⇒ 7≠10; ⇒ (2;12) is not solution.
for point (-2;-5), it means x=-2; y=-5:
-5-5=-2*5; ⇒ -10=-10, ⇒ (-2;-5) is solution.

You can find the slope using the points.
9-18 -9 9
--------- = ------- = -------
-14+10 -4 4
Next, you can find the equation of the line.
y-9=9/4(x+14)
y=9/4x+40.5
Plug in 0 for x.
y=9/4(0)+40.5
y=40.5
So, the y-intercept is (0,40.5)
Plug in 0 for y.
0=9/4x+40.5
-40.5=9/4
x=-18
So, the x intercept is (-18,0)
I hope this helps!

Esther is getting balloons for her father's birthday party. She wants each balloon string to be 6 feet long. At the party store,

lions [1.4K]

Answer: She needs 130 of string .

Step-by-step explanation:

Given: Length of each ballon string = 6 feet

Total number of ballons = 65

Total string required = ( Length of each ballon string) x (Total number of ballons)

= 6 x 65

= 390 feet

Since 1 foot = $\frac 13$ yard
