Write the equation of the line that goes through (-4,13) and (8,49).

algol [13]

Answer:

y=3x +25

Step-by-step explanation:

First calculate the slope:

m = (y1 - y2)/(x1-x2)

m = (49 - 13)/(8-(-4))

m= 36/12 = 3

so we have

y = 3x + b

subtitute a point:

49=3(8) + b

b=25

the equation is y=3x +25

What is the solutions of the inequality? 12x - 3x + 11 > 4x - ( 17 - 9x)

Alchen [17]

<span>Hello,
For this 12x-3x+11>4x-(17-9x)let's rewrite it as:
12x-3x+11>4x-17+9x
Now combine like terms:
9x+11>13x-17
Subtract 9x and add 17 to get:

28>4x
Divide by 4:
7>x or rewritten as:
x<7
Make sense?</span>
