Find the slope and y intercept.​
yan [13]

Step-by-step explanation:

the most common form of line equation is

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and since for b.

2 points are marked already :

(-3, 4) (3, -4)

x changes by +6 (from -3 to 3)

y changes by -8 (from 4 to -4)

the slope is -8/+6 = -8/6 = -4/3

the y-intercept is also clearly visible on the chart : the line crosses the y-axis precisely at (0, 0).

so, the y-intercept is 0.

\\ \sf\longmapsto 5x+5+4x-5=180

\\ \sf\longmapsto 5x+4x+5-5=180

\\ \sf\longmapsto 9x=180

\\ \sf\longmapsto x=\dfrac{180}{9}

\\ \sf\longmapsto x=20

  • y=x=20
  • z=5x+5=5(20)+5=100+5=105
