Answer:

3x + 5y = 15

Find gradient:

coordinates taken: (5, 0), (0, 3)

\rightarrow \sf \dfrac{y_2-y_1}{x_2-x_1}

\rightarrow \sf \dfrac{3-0}{0-5}

\rightarrow \sf -\dfrac{3}{5}

  • Here the y-intercept: 3
  • gradient: -3/5

equation:

\sf \bold{ y = m(x) + b}

\rightarrow \sf y = -\dfrac{3}{5} x + 3

\rightarrow  \sf y = -\dfrac{3}{5} x + \dfrac{15}{5}

\rightarrow  \sf 5y =-3x+15

\rightarrow  \sf 3x+5y =15

The value of x is 31

because straight line is equal to 180,so inorder to find the value of x you sum up all numbers and subtract by the the 180

59+52+38=149

180-149=31

therefore x=31

Two points located on are J(1,-4) and K(-2,8). What is the slope of ?
vodka [1.7K]

Answer:

-4

Step-by-step explanation:

The slope is usually a function of the differences in y divided by the differences in x, and it can be described in the following equation,

Slope = \frac{y_{1} - y_{2} }{x{1} - x{2}}     (1)

We can select any of the two points to be our first point, let's say, J(1,-4) is point 1, so J (x1,y1). In other words, x_1 = 1 and y_1 = -4 and by the same way, for K(-2,8). Therefore, x_2 = -2 while y_2 = 8. By substituting these values in equation 1, we can deduce the following

slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 - (-4)}{-2 - 1} = \frac{8 + 4}{-2 - 1} = \frac{12}{-3} = -4
