Question

Analyze the equations in the graphs to find the slope of each equation the y-intercept of each equation in the solution for the system of equations equation 1: y = 50x + 122

Answer 1

Given:

$y=50x+122\ldots\text{ (1)}$$y=1540-82x\ldots\text{ (2)}$

The general equation is

$y=mx+c$

m is a slope and c is the y-intercept.

From equation (1),

$\text{Slope = 50 and y intercept is 122}$

From equation (2)

$\text{Slope = -82 and yintercept is }1540$

From equation (1) and (2)

Substitute equation (2) in (1)

$1540-82x=50x+122$$50x+82x=1540-122$$132x=1418$$x=\frac{1418}{132}$$x=44$

Substitute in (2)

$undefined$
