Which of the following has a y-intercept of 3 y=3x+2 or x=3or y=2x+3 or y=x
1 answer:
Answer:
We conclude that the equation y=2x+3 has a y-intercept of 3.
Step-by-step explanation:
The slope-intercept form of the line equation
where
- m is the slope
- b is the y-intercept
Given the equation
y = 3x+2
comparing with the slope-intercept form y = mx+b
The slope-intercept of y = 3x+2 is: 2
Given the equation
x=3
Does not have a y-intercept.
Given the equation
y=x
comparing with the slope-intercept form y = mx+b
The slope-intercept of y=x is: 0
Given the equation
y=2x+3
comparing with the slope-intercept form y = mx+b
The slope-intercept of y=2x+3 is: 3
Thus, we conclude that the equation y=2x+3 has a y-intercept of 3.

Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (- 4, 0)
m = =
= 2
