A line with a slope of 1 passes through the point (18, 15). What is its equation in slope-intercept form? Write your answer usin
Setler79 [48]

Answer:

y = x - 13

Step-by-step explanation:

Given parameters:

  Slope of the line  =  1

  Coordinate = (18, 15)

Unknown:

Equation of the line in slope-intercept format = ?

Solution:

The equation of a line is expressed as;

         y  =  mx + c

where y and x are the coordinates

          m is the slope

          c is the y-intercept

Now, sine x = 18 and y = 5, let us find c;

        5 = 1(18) + c

      5 = 18 + c

       c = -13;

 The equation of the line is;

       y  = 1(x) + (-13)

       y = x - 13

I need help and i would appreciate it and can you explain (That's if you can explain)
Finger [1]

Answer:

x=-2

y=-3

Step-by-step explanation:

-9x+4y = 6

9x+5y = -33

We will add these together to eliminate x

-9x+4y = 6

9x+5y = -33

----------------

0x +9y =- 27

9y = -27

Divide by 9

9y/9 = -27/9

y =-3

We still need to find x

9x +5y = -33

9x +5(-3) = -33

9x-15 = -33

Add 15 from each side

9x+15-15 =-33+15

9x=-18

Divide by 9

9x/9 = -18/9

x = -2
