What is the equation of the line that passes through the points (6,8) and (-3,2)
Vikki [24]

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (6, 8) and (-3, 2). Substitute:

m=\dfrac{2-8}{-3-6}=\dfrac{-6}{-9}=\dfrac{2}{3}\\\\y-8=\dfrac{2}{3}(x-6)\qquad|\text{use distributive property}\\\\y-8=\dfrac{2}{3}x-4\qquad|+8\\\\y=\dfrac{2}{3}x+4\qquad|-\dfrac{2}{3}x\\\\-\dfrac{2}{3}x+y=4\qquad|\cdot(-3)\\\\2x-3y=-12

Answer:

point-slope form: y-8=\dfrac{2}{3}(x-6)

slope-intercept form: y=\dfrac{2}{3}x+4

standard form: 2x-3y=-12

Graph the function f(x)= -(x-2)^2 +4. In what form is this quadratic function written? _________________________. List the value
nevsk [136]

Answer:

see below

Step-by-step explanation:

f(x)= -(x-2)^2 +4

This is the vertex form of the equation for a parabola

y= a ( x-h)^2 +k  where (x,k) is the vertex of the parabola

a = -1   h= 2   k = 4

The vertex is ( 2,4)

The\ slope-intercept\ form:\\\\y=mx+b\\\\m-the\ slope;\ b-the\ y-intercept\ form

the\ slope:\\\\m=\frac{5\ miles}{1.4\ hours}=\frac{50}{14}\ mph=\frac{25}{7}\ mph\\\\so,\ therefore:\\\\\boxed{y=\frac{25}{7}x}

This diagram shows four small squares and one rectangle composed of 10 small.
horsena [70]

9514 1404 393

Answer:

  (A) yes; each small square could represent 10 units

  (B) no; there are a total of 14 small squares. No reasonable relationship maps this to 410

Step-by-step explanation:

(A) The total number of small squares is 14, so we expect any number represented by the diagram to be a multiple of 14. If each small square represents 10 units, then the 4 small squares represent 40 units, and the rectangle represents 100 units, for a total of 140 units being represented in the diagram. Andre is correct.

__

(B) The above argument suggests that 410 will not be reasonably represented by the diagram. To represent 410, we expect 4 tokens that each represent 10 of a smaller token. The rectangle of 10 squares would be such a token, but the diagram has only one of those, not 4 of them. Similarly, we expect 1 of a smaller token, but the diagram has 4 of them. In any event, 410 is not a multiple of 14, so there is no (integer) value that can be assigned to a small square that lets the diagram represent 410.

I do not agree with Diego.
