Answer:
(Slope intercept form)
(Slope point form)
Step-by-step explanation:
The slope of the line can be calculated as following:
The the equation of the line in slope point form is:
Where (
,
) is a point of the line.
Then you must susbtitute the point given and the slope and you obtain:
The intercept form is:
Where b is the y-intercept.
Solve for y from the equation of the line in slope point form obtained above, then:
Answer:
A.
Step-by-step explanation:
A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.
Choice B contradicts the previous statement.
Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.
Choice D is wrong because the y-intercept is where x = 0.
I hope this helps!
Since you're trying to find the side lenghts of a square, all we need to do is square root the area. So, the square root of 4 (the area) is 2.
So, all of the sides of the square are 2 meters long.
Answer:
yes these all are correct
