Answer:
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.
Step-by-step explanation:
Answer:
Positive
Step-by-step explanation:
Since there are two x-intercepts, -2 and 2, there is a positive discriminant. If the parabola was below the x axis and opened downwards, the discriminant would be negative.
Answer:
Right angle 90 degrees is always going to be a right angle.
Step-by-step explanation:
Answer:
The y-intercept refers to the y-coordinate of a point where a curve or a line, intersects the y-axis.
In the given equation, the y-intercept is ( 0, 9.5).
Step-by-step explanation:
We have been given the equation;
y=0.10x+9.50
The y-intercept is simply the y-coordinate of a point where the line intersects the y-axis. At this point, the value of x is usually zero.
y = 0.10 (0) + 9.50
y = 0 + 9.50
y = 9.50
is our y-intercept
