Write an equation of the line shown. Then use the equation to find the value of 2 when y = 185

x = 11, when y = 185

Step-by-step explanation:

Given:

(0, 20);

(2, 50)

Required:

Equation of the line;

Value of x, when y = 185

SOLUTION:

Equation of the line can be written using the slope-intercept formula, given as, .

m = slope =

b = y-intercept = the pointt at which the line cuts the y-axis = 20

Plug in the value into the formula to get the equation:

Use this equation to solve for x, when y = 185

(substitution)

x = 11, when y = 185

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

they would have to work 32 hours.
