Answer:

y=4x+7

Step-by-step

(-2,1) and (1,-11)

1)Rule you should use is run over rise aka slope

y²-y^1=

x^2-x^1=

(-11)-1=12

1-(-2)=3

12/3=4

slope =4

2)Rule of point slope intercept

y - y1 = m(x - x1)

y+1=4(x+2)

y+1=4x+8

   -1     -1

y=4x+7

What is an equatiom for the line with slope 2/3 and y-intercept 9​
earnstyle [38]

Answer:

y = (2/3)x + 9

Step-by-step explanation:

Equation of a straight line is y = mx + b. You are trying to finish the equation.

Note that:

m = slope = 2/3

b = y-intercept = 9

Plug in the corresponding numbers to the corresponding variables:

y = mx + b --> y = (2/3)x + 9

y = (2/3)x + 9 is your equation.

Jacob rode his bike 5 3/4 miles last week. This week,he rode 4 times as far as he rode last week. How many miles did Jacob ride
Bess [88]

Answer:

Hope this helps

Step-by-step explanation:

1. Make 5 3/4 into an improper fraction. That would be 23/4. 2. Write 4 in a fraction way. That would be 4/1. 3. Now do 23/4 X 4/1. That would be 92/4. 4. Turn it into a mixed number by doing 92 divided by 4. That would be 23. No fraction after 23. Jacob rode his bike 23 miles this week. :)

16: 10(-9) +4 = -90 +4 = -86

17. 7^2 - 7 = 49-7 = 42

18. -9^2 - -9 = 81+9 = 90

19. 10(5) +4 = 54, 3*54 = 162

20. 3*5 = 15, 10(15) +4 = 154
