Answer:
n=-4 x=-7
Step-by-step explanation:
It is y+1=0.9(x+4) because the formula is y - y1=m(x + x1) you only need one point and the slope. If you have two points, you need to find the slope by using the slope formula slope=y2-y1/x2-x1. Filling it in it would look like slope=7-(-1)/5-(-4). The double negatives cancel each other out and it turns to addition signs leaving us with slope=7+1/5+4 so the slope is 8/9 or 0.9. Now you can fill out the point-slope formula y+1=0.9(x+4)
10 x 12 = 120m² - 7 x 2 = 106m²
= 106m²

So the equation which will tell the amount of water is</h3><h3>
W= 24 + 32 T</h3>
Step-by-step explanation:
Given,
A water tank already contain 24 gallons of water before the pump was switched to fill it. The pump started 10:00 am and by 10:30 am the tank contained 40 gallons of water . By 1:00 pm the tank contained 120 gallons of water.
The pump filled the tank (40 -24) = 16 gallons in 30 mins.
The pump filled (16 × 2 ) gallons =32 gallons in 1 hour.
So the equation which will tell the amount of water is
W= 24 + 32 T
