Write the equation in slope-intercept form of the line that has a slope of 3 and contains the point (4, 9)?

Answer 1

y = mx + b --> slope-intercept form
y = 3x + b
substituting point(4, 9)
9 = 3(4) + b
9 = 12 + b
b = -3

therefore the equation is given by
y = 3x - 3

Answer 2

An equation of a line is continually written as y = mx + c the situation y is the y-coordinate, m is the gradient (slope), x is the x-coordinate and c is the y-intercept. by way of fact the line has a slope of two, => y = 2x + c and thinking it is composed of the factors (-a million, 4), => (4) = 2 (-a million) + c => 4 = -2 + c c = 6 subsequently, you gets y = 2x + 6 it is the equation of the line.

Answer 3

Slope intercept form: y = mx + b
where m = slope and b = y-intercept

You are given the following info:
m = 3
x = 4
y = 9

By direct substitution you can find b:

y = mx + b
9 = 3(4) + b
9 = 12 + b
-3 = b

Therefore, y = 3x - 3

Answer 4

Slope Intercept form formula

y = mx + b

- - - - - - - - -

3 = slope

(4, 9) = ordered pair

- - - - - - - - - -

y = mx + b

9 = 3(4) + b

9 = 12 + b

9 - 12 = 12 + b - 12

- 3 = b

The answer is b = - 3

- - - - - - - - - - -

The equation

y = 3(4) + ( - 3)

y = 3(4) - 3

- - - - - - - s-

Answer 5

since we have the slope intercept form w/c is equal to

y= mx + b,

i have a formula in finding the equation in slope-intercept form.
which is:

y - y1 = m ( x - x1)

since we have the (4,9) as our (x1,y1) and m= 3, we can get the equation..., just simply substitute all the given data to the formula I've given.. Substituting all the given data, we will get;

y - 9 = 3 ( x - 4)

simplifying....... we will get...

y - 9 = 3x -12

after that..., transform the results in the form y = mx + b, and we will get.....;

y = 3x - 3

that is the equation in slope- intercept form......

Answer 6

y-9=3(x-4)
y=3x-3
