Linear function is, y = 2 x + 3.
What does the y-intercept of this relationship represent?
- The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y.
- The slope indicates the rate of change in y per unit change in x.
- The y-intercept indicates the y-value when the x-value is 0.
Which is a y-intercept of the graphed function?
- The y -intercept of a graph is the point where the graph crosses the y -axis.
- (Because a function must pass the vertical line test , a function can have at most one y -intercept . )
- The y -intercept is often referred to with just the y -value.
How do you find the y-intercept of a graph?
- On a graph, the y-intercept can be found by finding the value of y when x=0.
- This is the point at which the graph crosses through the y-axis.
According to the question:
From the points we can see the y-intercept of the line is 3 as it passes through point (0, 3).
y = 2 x - 4
y-intercept is -4 ≠ 3, incorrect.
y = 2 x - 3
y- intercept is -3 ≠ 3, incorrect.
y = 2 x + 3
y- intercept is 3 = 3, correct.
