What is the slope of the graph of y= -5/3x + 3/4

Lesechka [4]

Answer:

slope = - $\frac{5}{3}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{5}{3}$ x + $\frac{3}{4}$ ← is in slope- intercept form

with slope m = - $\frac{5}{3}$

Can someone show me how to even start with 1 and 2?

diamong [38]

All you need to know is that

$\displaystyle \lim_{x\to\infty}a^x=\begin{cases} \infty \text{ if } a>1\\1 \text{ if } a=1\\0 \text{ if } 0\leq a$

So, the first function grows exponentially and the second decays exponentially. The rate of growth/decay are the bases of the exponentials, which means 1.08 and 0.205
