Analyze the equations in the graphs to find the slope of each equation the y-intercept of each equation in the solution for the

natta225 [31]

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)

$undefined$
