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
