Answer: Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.
Step-by-step explanation:
Answer:
slope = [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 4) ← 2 points on the line
m = [tex]\frac{4-(-3)}{3-(-1)}[/tex] = [tex]\frac{4+3}{3+1}[/tex] = [tex]\frac{7}{4}[/tex]

Help please.
Is algebra.
Answers
Answer:
3
Step-by-step explanation:
To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).
Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).
So we have: (87-45) / (29-15)
This can be simplified to: 42/14, or 3.
