Find the slope of the line through each pair of points

NNADVOKAT [17]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

95)

$(-13,\ -10)\to x_1=-13,\ y_1=-10\\(16,\ 16)\to x_2=16,\ y_2=16$

substitute:

$m=\dfrac{16-(-10)}{16-(-13)}=\dfrac{16+10}{16+13}=\dfrac{26}{29}$

96)

$(6,\ -16)\to x_1=6,\ y_1=-16\\(-15,\ 9)\to x_2=-15,\ y_2=9$

substitute:

$m=\dfrac{9-(-16)}{-15-6}=\dfrac{25}{-21}=-\dfrac{25}{21}$

97)

$(12,\ -11)\to x_1=12,\ y_1=-11\\(14,\ -12)\to x_2=14,\ y_2=-12$

substitute:

$m=\dfrac{-12-(-11)}{14-12}=\dfrac{-12+11}{2}=-\dfrac{1}{2}$

OK. I think you already know how to solve it. I will give short solutions now.

98)

$m=\dfrac{15-(-3)}{8-(-14)}=\dfrac{18}{22}=\dfrac{9}{11}$

99)

$m=\dfrac{3-(-5)}{-7-3}=\dfrac{8}{-10}=-\dfrac{4}{5}$

100)

$m=\dfrac{-8-8}{-11-0}=\dfrac{-16}{-11}=\dfrac{16}{11}$

101)

$m=\dfrac{13-(-5)}{-13-(-13)}=\dfrac{18}{0}!!!-\boxed{NOT\ EXIST}$

102)

$m=\dfrac{18-1}{-10-2}=\dfrac{17}{-12}=-\dfrac{17}{12}$

103)

$m=\dfrac{19-14}{7-(-17)}=\dfrac{5}{24}$

104)

$m=\dfrac{12-0}{-6-4}=\dfrac{12}{-10}=-\dfrac{6}{5}$

Write a polynomial of lowest degree with zeros 1/3 (multiplicity 2) and -1/4 (multiplicity 1) and with f(0)=-3

Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

y = C(x - 1/3)(x - 1/3)(x + 1/4)

y = C(x² - 2/3x + 1/9)(x + 1/4)

y = C(x³ - 2/3x² + 1/4x² + 1/9x - 1/6x + 1/36)

y = C(x³ - 5/12x² - 1/18x + 1/36)

now to account for the y intercept (x = 0)

-3 = C((0)³ - 5/12(0)² - 1/18(0) + 1/36)

-3 = C(1/36)

C = -108

distribute the C term across all variables.

y = -108x³ + 45x² + 6x - 3

we can verify our solution using a plotting calculator.

Rewrite the following equation in slope-intercept form. 5x + 7y = 7 Write your answer using integers, proper fractions, and impr

pogonyaev

Answer:
y = (-5/7) x + 1

Explanation:
The slope-intercept form of the line has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
5x + 7y = 7

To put this in slope-intercept form, we will need to isolate the y as follows:
5x + 7y = 7
7y = -5x + 7
y = (-5/7) x + (7/7)
y = (-5/7) x + 1
where:
m is the slope = -5/7
c is the y-intercept = 1

Hope this helps :)
