Answer:

Yes

Step-by-step explanation:

Look up Desmos, it is graphing calculator... it will really help. REAL EXPLANATION: You put one point on -4, then do rise over run (2/1x), thus go up to over one. So on and so forth; this will result in a linear line.

What is an equation of the line that passes through the points (0,3) and (5,−3)? Put your answer in fully reduced form.

Vinil7 [7]

Using the "gradient, two-point form", we have:
$\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1}$
From the given data, we have that
$y2 = - 3 \\ y1 = 3 \\ x2 = 5 \\ x1 = 0$
Therefore, substitute in the given values:
We have that:
$\frac{y - (3)}{x - (0)} = \frac{( - 3) - (3)}{(5) - (0)}$
Simplify further
$\frac{y - 3}{x} = \frac{ - 6}{5}$
Multiply both sides by the LCM, 5x:
$5x( \frac{y - 3}{ x} ) = 5x( \frac{ - 6}{5} )$
Simplify:
$5( y - 3) = x( - 6)$
$5y - 15 = - 6x$
Note that the equation of a straight line is given by Ax + By = C where A and B are coefficients of x and y respectively. C is the constant. Hence:
6x+5y=15

If g(x)= 4x^2-16 we’re shifted 9 units to the right and 1 down, what would the new equation be

ser-zykov [4K]

Answer:

Step-by-step explanation:

A shift along the x-axis is the opposite in the graph than in the equation. Rather than the x-intercept(s) being negative if the equation is x - n, they become positive; likewise for the other way around. A is the only answer that follows this rule. However, the y-intercept is y = n, so if n is negative, y gets shifted down rather than up.
