Choose the linear equation in slope-intercept form given the table of values.
KiRa [710]

Answer:

A. y = 6x -1

Step-by-step explanation:

take two coordinates: (-1,-7) , (2,11)

slope:

\frac{y2-y1}{x2-x1}

\frac{11--7}{2--1}

\frac{18}{3}

6 ....slope(m)

equation:

y - y1 = m(x - x1)

y - 11 = 6(x-2)

y = 6x -12 + 11

y = 6x -1

Given g(x) = 3x + 14 , find x if g(x) = 20
Helga [31]

Answer: x = 2

Step-by-step explanation: If g(x) = 3x + 14, and g(x) = 20 also, you first can set 3x+14 = 20. To find the value of x, you want to isolate the variable. You can subtract 14 from both sides to get 3x = 6. Finally, to find out the value of x, divide 3 from both sides. This leaves you with x = 2. You can check this by plugging two back into the original equation 3 times 2 = 6, and 6 plus 14 equals 20.
