Write an equation of the line that passes through the given points. (-1,5) and (2, - 7)

Vanyuwa [196]

Answer:

The equation of the straight line is 4x +y = 1

Step-by-step explanation:

Step(i):-

Given points are (-1,5) and ( 2,-7)

Slope of the line

$m =\frac{y_{2}-y_{1} }{x_{2} -x_{1} } =\frac{-7-5}{2-(-1)} = \frac{-12}{3} = -4$

slope of the line m = -4

Step(ii):-

The equation of the straight line passing through the point (-1,5) and having slope 'm' = -4

$y - y_{1} = m( x-x_{1} )$

y - 5 = -4 ( x-(-1))

y -5 = -4 x -4

4 x + y -5 +4=0

4x +y -1 =0

Final answer:-

The equation of the straight line is 4x +y = 1

n200080 [17]

Answer:

The probability that a plant had white flowers is 0.70

Step-by-step explanation:

Given:

Number of plants with white flowers=769

Number of plants with purple flowers= 326

To Find:

The probability that a plant had white flowers is=?

Solution:

Total number of flowers plants = Number of plants with white flower + Number of plants with purple flowers

Total number of flowers plants = 769+ 326

Total number of flowers plants = 1095

Probability that the plant had white flowers = $\frac{769}{1095}$

Probability that the plant had white flowers =0.70

Probability that the plant had purple flowers = $\frac{326}{1095}$

Probability that the plant had purple flowers = 0.29
