Answer:

$y=\frac{6}{5}x-24$

Step-by-step explanation:

$Since\ the\ yellow\ points\ are\ \left(20,0\right)and\ \left(70,60\right)$
$so,\ set\ the\ equation\ of\ this\ is\ y=mx+b$
$\rightarrow0=m\times20+b$
$60=m\times70+b$

$get\ m=\frac{6}{5},b=-24$

$so,\ the\ slope-intercept\ form\ of\ it\ is$
$y=\frac{6}{5}x-24$
$\left\{Substitution\ method\right\}$

Simpligy the expression 7(x+7)-3(x+3)

Irina18 [472]

We will use the distributive property, where $a(b+c) = ab+ac$ and $a(b-c) = ab-ac$ .

$7(x+7)-3(x+3)$

$=7x+49-(3x+9)$

$=4x+40$

Therefore, the simplified expression is 4x+40.
