The point-slope form of the equation of the line that passes through (–9, –2) and (1, 3) is y – 3 = (x – 1). What is the slope-i

ntercept form of the equation for this line?
y =1/2 x + 2
y = 1/2x – 4
y = 1/2x + 5/2
y = 1/2x – 7/2

(-9,-2) (1,3)
slope = (3 - (-2) / (1 - (-9) = 5/10 = 1/2

y - y1 = m(x - x1)
slope(m) = 1/2
(1,3)...x1 = 1 and y1 = 3
sub
y - 3 = 1/2(x - 1)
y - 3 = 1/2x - 1/2
y = 1/2x - 1/2 + 3
y = 1/2x - 1/2 + 6/2
y = 1/2x + 5/2 <=== slope intercept form

Answer: y=\dfrac{1}{2}x+\dfrac{5}{2}

Step-by-step explanation:

Equation of a line passing through points (a,b) and (c,d) is given by :-

(y-b)=\dfrac{d-b}{c-a}(x-a)

Similarly, the equation of line passing through (-9, -2) and (1, 3) is given by :-

(y-3)=\dfrac{3-(-2)}{1-(-9)}(x-1)

(y-3)=\dfrac{3+2}{1+9)}(x-1)

(y-3)=\dfrac{5}{10}(x-1)

(y-3)=\dfrac{1}{2}(x-1)

(y-3)=\dfrac{1}{2}x-\dfrac{1}{2}

Add 3 both sides , we get

y=\dfrac{1}{2}x-\dfrac{1}{2}+3

y=\dfrac{1}{2}x+\dfrac{(2)(3)-1}{2}

y=\dfrac{1}{2}x+\dfrac{5}{2}

Hence, he slope-intercept form of the equation for this line :

y=\dfrac{1}{2}x+\dfrac{5}{2}

Describe one difference between rewriting a literal equation and solving an equation in one variable.
sesenic [268]

Literal equation:

we know that

literal equation is equation of more one variable

for example: 2x+3y=1

And we can solve such equations only if we are given two such equation

because it has two variables

One variable equation:

such equation has single variables

for example:

3x=21

we don't need any other equation

we can solve for variables from single equation itself

because it has only one variable that is x

Hannah is asked to convert the number 0.00000305 to scientific notation. Her answer is 3.05 × 106. Which statement best describe
Sophie [7]

Answer: if u mean 3.05 x 10^6 then Hannah is correct.

Step-by-step explanation:

With scientific notations you should have one number on the left side of the decimal so 3.05 is correct and since you move the decimal to the right six times you would get 3.05 * 10^6
