Find the slope of the line that passes through (4, 9) and (1, 4).
alexandr1967 [171]

We can use the points (1, 4) and (4, 9) to solve.

Slope formula: y2-y1/x2-x1

= 9-4/4-1

= 5/3 or 1 2/3

Best of Luck!

Factor 1 and 2. You do NOT need to show or explain steps for 1-2.
kogti [31]

Answer:

Step-by-step explanation:

x² + 9x + 18 = x² + 6x + 3x + 18

                   = x(x + 6) + 3(x + 6)

                   = (x + 3)(x + 6)

x² + 16x + 63 = x² + 9x + 7x + 63

                     = x(x + 9) + 7( x+ 9)

                     = (x + 7)(x + 9)

y² + 13y + 36 = y²+ 9y + 4y + 36

                     = y(y + 9) + 4(y + 9)

                     = (y + 4)(y + 9)

(a). Factored form of the expression (y² + 13y + 36) is (y + 4)(y + 9).

Therefore, Lyndsey's answer is wrong.

(b). Factors are (y + 4) and (y + 9).

(c). Factored form of the expression should be (y + 4)(y + 9) instead of Lindsey's answer (y + 6)(y + 6).

Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x) = 2x + 3 The function g of x g
Likurg_2 [28]
Because g(x) passes from 1,0 to 1,4, we can say that it has a slope of 0. f(x) has a slope of 2.
