Answer:
The x - intercept of the line is (-4, 0).
Step-by-step explanation:
The <em>x</em>-intercept is the point from which the graph passes through the <em>x</em>-axis.
At the <em>x-</em>intercept y = 0.
The provided line is:
Substitute y = 0 in this equation to determine the <em>x</em>-intercept as follows:
Thus, the <em>x</em>-intercept is (-4, 0).
Refer to the graph below.
Answer:
x = ±11/4
Step-by-step explanation:
Rewrite -16x^2+121=0 as 16x^2 - 121=0 and then as 16x^2 = 121.
Take the square root of both sides. This returns 4x = ±11, and so:
x = ±11/4
Answer:
Step-by-step explanation:
We were given the slope formula;
This line is vertical if the denominator is zero.
That is when 
This implies that;
Justification;
When , then, the line passes through;
and 
The slope now become
The equation of the line is
This implies that;
... This is the equation of a vertical line.
If you have a fraction, take one number and put a different number on top or underneath, for example if you have 2 cats and 3 dogs, the ratio from cats to dogs would be 2:3 but if you did 2 cats to the total number of animals, you would add 2 and 3 and get 5, so the ratio would be 2:5.
