Write the equation of line that passes through (-1,3) and (-5,-3)

Black_prince [1.1K]

Answer:

$y = \frac{3}{2} x + 4 \frac{1}{2}$

Step-by-step explanation:

y=mx+c

where m is the gradient and c is the y-intercept of the line

Let's find the gradient of the line first.

$gradient = \frac{y1 - y2}{x1 - x2}$

Using the above formula,

$gradient \: of \: line \\ = \frac{3 - ( - 3)}{ - 1 - ( - 5)} \\ = \frac{3 + 3}{5 - 1} \\ = \frac{6}{4} \\ = \frac{3}{2}$

Subst. the gradient into m:

$y = \frac{3}{2} x + c$

Now, find the value of c by substituting a coordinate into the above equation.

when x=-1, y=3,

$3 = \frac{3}{2} ( - 1) + c \\ 3 = -\frac{3}{2} + c \\ c = 3 + \frac{3}{2} \\ c = 4 \frac{1}{2}$

Therefore the equation of the line is

$y = \frac{3}{2} x + 4\frac{1}{2}$

I can someone evaluate this I don’t understand? Question: 8. Evaluate the piecewise-defined function at the indicated inputs.

enot [183]

Answer:

Step-by-step explanation:

Your function is split into 4 parts.

We want to use the piece that includes x=6.

This only included in the inequality that says x is greater than or equal to 5. Since that is, we use the expression that corresponds to that to find f(6).

f(6)=2(6)-6

f(6)=12-6

f(6)=6

answer as a mixed number if possible. A bowl of cereal had 3 3/6 grams of sugar in it. If Victor ate 2 bowl8a week, how many gra

GrogVix [38]

<em>7 grams of sugar</em>

<h2>Explanation:</h2>

________________________________________

I'll assume your answer is as follows:

<em>A bowl of cereal had 3 3/6 grams of sugar in it. If Victor ate 2 bowl a week, how many grams of sugar would he have eaten?</em>

________________________________________

If so, then we know that:

A bowl of cereal had 3 3/6 grams of sugar in it.

Victor ate 2 bowl a week

In other words, the total of sugar he ate can be calculated as:

$3\frac{3}{6}\times2 \\ \\ Converting \ mixed \ fraction \ into \ improper \ fraction: \\ \\ =(3+\frac{3}{6})\times2 \\ \\ =(\frac{3(6)+3}{6})\times 2 \\ \\ =(\frac{21}{6})\times 2 \\ \\ =(\frac{7}{2})\times 2 \\ \\ =7$

So <em>he'd have eaten 7 grams of sugar</em>
