Which line has a slope of zero and goes through (5, -8)
goblinko [34]

Answer:

y=-8

Step-by-step explanation:

From the information given, we know that the slope of the line is 0. Let's make an equation in y=mx+b form with what we know.

y=0x+b

We also have a point on the line, (5, -8). We can plug these two numbers for x and y to find b and complete the equation. -8 goes in as y and 5 goes in as x.

-8=0(5)+b

Now just solve for b.

-8=0+b

b=-8

We now know that b is -8 and can complete the equation.

y=0x-8

y=-8

Answer:

7+9+11+3=30 (total)

(13)-

\frac{9}{30}  =  \frac{3}{10}

(14)-

\frac{13}{52}  =  \frac{1}{4}

(15)-

\frac{7}{30}  +  \frac{11}{30}  =  \frac{18}{30}   =  \frac{9}{15}  =  \frac{3}{5}

(16)-

\frac{13}{52}  +  \frac{13}{52}  =  \frac{26}{52}  =  \frac{1}{2}

(17)- Experimental and theoretical are not the same but within 10% of each other .
