Question

Need help with this ( finding slope ) plz

Answer 1

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 340) and (x₂, y₂ ) = (4, 292) ← 2 ordered pairs from table

m = $\frac{292-340}{4-0}$ = $\frac{-48}{4}$ = - 12

(0, 340 ) → gives the y- intercept b = 340

The equation is of the form

y = mx + b ( m is the slope and b the y- intercept ), thus

y = - 12x + 340
