$x+y=40\\
x-y=8\\
-----\\
2x=48\\
x=24\\\\
24+y=40\\
y=16$

a - b = 8
<u>+ a + b = 40
</u> 2a = 48
a = 24

a - b = 8
24 - b = 8
b = 16

(0,30), (1,20)
(20-30)/(1-0) = -10/1 = -10 slope
We know y intercept is 30
Equation: y = -10x + 30

Slope of (-20,9) (14,9)

skelet666 [1.2K]

Y2-y1/x2-x1 is slope so

9-9/14-(-20) so you get 0/34 which means there is no slope since they have the same y (the equation would be y=0x+9 therefore y=9)
Which makes sense since the equation is a straight line

Write an equation that represents degrees fahrenheit in terms of degrees celsius. let xx represent the temperature in degrees ce

IgorC [24]

As we know Conversion from fahrenheit to celsius is
$F - 32 = \frac{9C}{5}$

We can write it also as

$F = \frac{9C}{5}+32$

F as y and C as x then we can write it as

$y = \frac{9x}{5} + 32$
