Ratling [72]

Answer:

Your answer will be

y=2x-15.5

Step-by-step explanation:

Hi, there you must know the slope-intercept form which is

y=mx+b

m=slope

b=y-intercept

You can also use

the slope formula which is

$\frac{y_2-y_1}{x_2-x_1}$

in this case

it will look like this

$\frac{-7.5-(-3.5)}{6-4}$ = $\frac{-4}{2}$ =-2

So the slope is -2

Now we will find the y-intercept

-7.5=2(4)+b

-7.5=8+b Subtract 8 both sides

-15.5=b

Your y-intercept is -15.5

Hope this helps

f + g =3y

f - f + g = 3y - f

g = y - f

Answer:

$f$ < $132$

Step-by-step explanation:

$Greetings!$

$I'm~Isabelle~Williams~and~I~will~be~answering~your~question!$

$Subtract~16~from~both~sides:$

$\frac{f}{4} +16-16$ < $49-16$

$Simplify:$

$\frac{f}{4}$ < $33$

$Now,~multiply~both~sides~by~4:$

$\frac{4f}{4}$ < $33\times4$

$f$ < $132$

$Hope~my~answer~helps!~Have~a~great~day~ahead!$
