The graph of a linear relationship has a slope of -5 and passes through the point (2,-12). Write the equation of the line in slo
kakasveta [241]

Answer:

To graph the line mark off the 2 points and draw a line through them.

Step-by-step explanation:

The slope = (-2-7) / (-3-0)

= -9/-3

= 3.

The value of b is found using the point-slope form of a line:

y - y1 = m(x - x1)

using m = 3, (x1, y1) = (0, 7):

y - 7 = 3(x - 0)

y = 3x + 7.

Sort each equation according to wether it has one solution, infinitely many solutions, or no solution
katovenus [111]

Answer:

5(x - 2)=5x-7 has no solution

-3(x - 4)=-3x+12 infinitely many solutions

4(x+1)=3x+4 no solution

-2(x - 3)=2x-6 infinitely many solution

6(x + 5)=6x+11 no solution

Step-by-step explanation:

5(x - 2)=5x-7

-3=0

-3(x - 4)=-3x+12

0=0

4(x+1)=3x+4

x=0

-2(x - 3)=2x-6

0=0

6(x + 5)=6x+11

30=11

I hope this helps.

John is driving around town. When he reaches the gas station, he notes that he has traveled 20 miles. He reaches home 2 hours la
Dmitriy789 [7]

Answer:

d = 5t + 20

Step-by-step explanation:

d represents the distance and t represents the time, in hours

Let he equation which model this situation ⇒ d = a t + b

Where a and b are constant.

Let the gas station is the starting point

So, at gas station t = 0 , d = 20

∴ 20 = 0 * a + b ⇒ b = 20

When he reaches home 2 hours later notes that he has traveled 30 miles.

and with substituting with b = 20

∴ 30 = 2 * a + 20

2a = 30 - 20 = 10  ⇒ a = 10/2 = 5

∴ d = 5t + 20

The equations that can be used to model this situation <u>d = 5t + 20</u>
