Given the point (-4, 2) and the y intercept (0, -5) write the equation of the line in slope-
laila [671]

The equation of the line in slope - intercept form is y=\frac{-7}{4}x-5


Explain what the slope-intercept form is?

Simply put, the slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible. This expression is sometimes referred to as y = mx + b form


Given:
x = -4 , y = 2 and b = -5

y = mx + b

2 = m (-4) + (-5)

m = \frac{-7}{4}
By putting the value of m we get equation of line
y=\frac{-7}{4}x-5

What is the probability that a random sample of 1414 second grade students from the city results in a mean reading rate of more
Sonbull [250]

Answer with explanation:

Number of second grade students who are considered for sample =1414

Number of words that is being read in a Minute = 9292 words per minute

If number of students will be more than half of 1414, that is if, they can read or their reading rate is more than 9292 words per​ minute, then we can say that the sample chosen is Appropriate.

⇒Required Probability,that sample of 1414 students can read  9292 words per​ minute

                   =\frac{707+x}{1414} \text{Where }, [1 \leq x\leq 707]

Betsy has ten and one half ounces of gold and and uses four fifths of it to make earrings. How much gold does she use to make th
andrew11 [14]

Answer:

Betsy uses  8\frac{4}{10} gold to make the earrings

Step-by-step explanation:

Given:

Amount of gold with Betsy =  ten and one half ounces

Amount of gold Betsy used to make earrings =  four fifths  

To Find:

How much gold is used by Betsy to make earrings = ?

Solution:

Let the quantity of gold used by Betsy to make earring be X

Then

X  =   four fifths  of  ten and one half

X  = \frac{4}{5} of 10 \frac{1}{2}

X = \frac{4}{5} \times \frac{20 + 1}{2}

X = \frac{4}{5} \times \frac{21}{2}

X=  \frac{84}{10}

Reducing the fraction to lower terms and converting into mixed fraction we get,

X=  8\frac{4}{10}
