Answer:
see below
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (-5- -7.5)/ ( 2 - -3)
= (-5+7.5) / ( 2+3)
= 2.5 /5
=1/2
Then using the slope intercept equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x+b
Using a point from above
-5 = 1/2(2) +b
-5 =1+b
Subtract 1 from each side
-6 = b
We have the y intercept
y = 1/2x-6
Tahlia forget to find the y intercept for the equation

Each student should do 1/4 of one board or 1/8 of both boards. This is because 8÷2 is 4, which means 4 people need to work together on one board.
Answer:
<h2>149 times.</h2>
Step-by-step explanation:
Let n be the number we are looking for.
The we have to solve this equation:
1999 - 7n = 1701 - 5n
⇔ 1999 - 1701 = 7n - 5n
⇔ 298 = 2 n
⇔ n = 298/2
⇔ n = 149
<u><em>Verification</em></u> :
1 999 - 7×149 = 956
1 701 - 5×149 = 956
