Y - (-1) = ⁻⁵/₇[x - (-4)]
y + 1 = ⁻⁵/₇(x + 4)
y + 1 = ⁻⁵/₇(x) - ⁵/₇(4)
y + 1 = ⁻⁵/₇x - 2⁶/₇
- 1 - 1
y = ⁻⁵/₇x - 3⁶/₇
Step 1: Find the slope<span> of the </span>line<span>. To find the </span>slope<span> of the given </span>line<span> we need to get the </span>line<span> into </span>slope-intercept form<span> (</span>y<span> = mx + </span>b), which means we need to solve fory<span>: The </span>slope<span> of the </span>line<span> 3x – 5y = 9 is m = </span>3<span>/5. Therefore, the </span>slope<span> of the </span>line parallel<span> to this </span>line<span> would </span>have<span> to be m = </span>3<span>/5.

Divide the number & Multiply
Answer:
6.27
Step-by-step explanation:
We are to obtain the standard deviation of the given values :
{24, 18, 31,25, 34}
The standard deviation = √(Σ(x - mean)²/ n)
The mean = (ΣX) /n
Using calculator to save computation time :
The standard deviation, s = 6.27 (2 decimal places)
Well u do 31.2 x 18 which is 561.6 then u divide by 2 because the formula for a triangle is base x height divided by 2 so It is 280.8
