have a good day :)
Step-by-step explanation:
Answer:
slope or gradient of a line is a number that describes both the direction and the steepness of the line.
The gallons of the first brand of antifreeze should be 60 gallons.
The gallons of the second brand of antifreeze should be 90 gallons.
<h3>What are the linear equations that represent the question?</h3>
0.2f + 0.45s = 52.50 (0.35 x 150) equation 1
f + s = 150 equation 2
Where:
- f = gallons of the first antifreeze
- s = gallons of the second antifreeze
how many gallons of each brand of antifreeze must be used?
Multiply equation 2 by 0.2
0.2f + 0.2s = 30 equation 3
Subtract equation 3 from equation 2
0.25s = 22.50
s = 22.50 / 0.25
s = 90
f = 150 - 90 = 60 gallons

Answer:
y = 5x - 7
Step-by-step explanation:
(x₁ , y₁) = ( 2 , 3) & (x₂ , y₂) = (-1 , -12)
Slope = 
m = 5 & (x₁ , y₁) = ( 2 , 3)
Equation of the line: y - y₁ = m(x -x₁)
y - 3 = 5(x - 2)
y - 3 =5x - 2*5
y - 3 = 5x - 10
y = 5x - 10 + 3
y = 5x - 7
