Question

What is the linear equation?

Answer 1

Easiest way is to use point slope form. So (y-901) = (99/60)(x-60). Original formula is y-y1 = m(x-x1).

Answer 2

Answer:   $\bold{y=-\dfrac{33}{20}x+1000}$

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx + b   where,

• m is the slope          
• b is the y-intercept

The information provided in the graph is:

• $m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-99}{60}=-\dfrac{33}{20}$
• b = 1000   (the y-value when x = 0)

Input the m and b-values above into the slope-intercept equation to get:            $y=-\dfrac{33}{20}x+1000$
