= 5x + 35 = -3
- 35 = -35
5x = -38
/ 5 = / 5
x = -7.6
Slope of the line passing through (-5,-4) and (-1,3)is 1.75
The slope formula
slope = (y₂ - y₁) / (x₂ - x₁)
Notice that the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
The points belong to an increasing, linear function.
Equation: y = 1.75x + 4.75.
m=7/4=1.75.

b and d can be eliminated because there are multiple solutions.
answer: A, because it shows all solutions to the equation
Answer:
55+14sqrt6
Step-by-step explanation:
Answer:
30.1%
Step-by-step explanation:
The increase in price (markup) is ($3.45 - $2.65) = $0.80.
The increase in price (as a decimal fraction) is 0.80/2.65, or 0.301; as a percentate, this is 30.1%
