Answer:

f(x)=6x+15

Step-by-step explanation:

first you find the gradient of the equation with the gradient formula by using the two given points

the gradient is 6, so using the slope equation which is y=mx+b sub 6 into the gradient

you then get y=6x+b

to find b just sub in any of the points and solve the equation.

ps. f(x) essentially stands for a y so don't get confused

hope this helps :)

Answer:

y = 6x + 15.

Step-by-step explanation:

The slope of the line joining these 2 points =

(9-3)/(-1-(-2))

= 6/1

= 6

Use the point-slope form of a straight line:

y - y1 =m(x - x1)   Here m = 6 and (x1, y1) will be  (-2, 3), so:

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

y - 3 = 6(x + 2)

y = 6x + 12 + 3

y = 6x + 15.

Need help on answering number 13.
Genrish500 [490]
You can find the value of y when you substitute the x value into the equation.

Since x = 3, the equation becomes:
y = 3 + 5

The answer to question 13 is y = 8
