How do you write (-2,-4),(-3,-3) into slope intercept form

zzz [600]

Answer- $y=−3x+9$

Step-by-step explanation:

First, we will write and equation in point-slope form and then convert to slope-intercept form.

To use the point-slope form we must first determine the slope.

The slope can be found by using the formula : $m=y2−y1x2−x1$

<em>Where </em> $m$ is the slope and $(x1,y1) and (x2,y2$ ) are the two points on the line.

Substituting the values from the points in the problem gives: $m=3−−32−4m=3+32−4m=6−2=−3$

We can now use this calculated slope and either point to write the equation in point-slope form.

The point-slope formula states: $(y−y1)=m(x−x1)$

Where $m$ is the slope and $(x1y1)$ is a point the line passes through.

Again, substituting gives: $(y−−3)=−3(x−4) (y+3)=−3(x−4)$ We can now convert this to slope-intercept form.

The slope-intercept form of a linear equation is: $y=mx+b$

Where $m$ is the slope and $b$ is the y-intercept value.

We can solve our equation for $y:$

$(y+3)=−3(x−4) y+3=(−3×x)−(−3×4)y+3=−3x−(−12)y+3=−3x+12y+3−3=−3x+12−3y+0=−3x+9y=−3x+9$

This took me so long to type lol, hope this helps you and have a great day noon or night! <3 ❤️

Give four reasons why you think mathematics should be taught in primary schools

eimsori [14]

Answer:

Mathematics offers children a powerful way of communicating. They learn to explore and explain their ideas using symbols, diagrams and spoken and written language. Studying mathematics stimulates curiosity, fosters creativity and equips children with the skills they need in life beyond school.

Of the students who eat in a certain cafeteria, each student either likes or dislikes lima beans and each student either likes o

spayn [35]

Answer: There are 32 students who like brussels sprouts but dislike beans.

Step-by-step explanation:

Since we have given that

Number of students eat in the cafeteria = 120

Fraction dislike lime beans = $\dfrac{2}{3}$

Fraction who dislike lime beans and brussles sprouts both = $\dfrac{2}{3}\times \dfrac{3}{5}$

Fraction who dislikes lime beans but not brussles is given by

$\dfrac{2}{3}(1-\dfrac{3}{5})\\\\=\dfrac{2}{3}\times \dfrac{2}{5}\\\\=\dfrac{4}{15}$

So, Number of students who like brussels sprouts but dislike lima beans is given by

$\dfrac{4}{15}\times 120\\\\=32$

Hence, there are 32 students who like brussels sprouts but dislike beans.

If possible, carry some factor outside the root sign: Radical please help

krek1111 [17]

Step-by-step explanation:

For the square roots, write the radicand as a multiple of a perfect square. For example:

√27 = √(9 × 3) = 3√3

√72 = √(36 × 2) = 6√2

√¾ = √(¼ × 3) = ½√3

For the cube roots, write the radicand as a multiple of a perfect cube. For example:

∛16 = ∛(8 × 2) = 2∛2

∛(27/8) = 3/2
