Answer:
y = 2x - 7
Step-by-step explanation:
The question is asking for slope-intercept form, y = mx + a.
Given:
(1, -5) and (9, 11)
Find the slope (m) between the two points:
m = (y2 - y1) / (x2 - x1)
x1 = 1
x2 = 9
y1 = -5
y2 = 11
m = ( 11 - (-5) )/(9 - 1)
= 16/8
m = 2
y = 2x + a
Use one of the two points to find a (I will use (1, -5)):
-5 = 2(1) + a
-5 = 2 + a
-7 = a
a = -7
y = 2x + (-7)
y = 2x - 7
Answer:
Step-by-step explanation:
5/3 *2=10/6
10/6-6/6=4/6
Answer:320
Step-by-step explanation:
for any square or rectangle the formula for area is <em>l*w </em>means length times width so for this particular square the length is 16 and the width is 20 so multiply the two and you get 320 hope this helps
The ratio of male fishes to female fishes is 3 : 2
<u>Solution:</u>
Given, male punky fish = 9 stripes
Female punky fish = 8 stripes.
Total stripes = 86
<em><u>Finding the ratio of male fish to female fish:</u></em>
Let the number of male fishes be "m", and the number of female fishes be "n"
The, given that, total strips = 86
which means, total male strips + total female stripes = 86


The only values that can satisfy above equation are m = 6 and n = 4
Now, ratio of male fishes to female fishes = m : n = 6 : 4 = 3 : 2
Hence, the ratio of male fishes to female fishes is found out as 3 : 2
