Strike441 [17]

Answer:

x^2 + 2x+1

Step-by-step explanation:

g(x) = x^2

Replace x with x+1

g(x+1) = (x+1)^2 = (x+1)(x+1)

FOIL

g(x+1) = x^2+x+x+1 = x^2 + 2x+1

Which equation represents the line that passes through the points (-4, 0) and (0, 6)
skad [1K]

Answer:

y = 1.5x + 6

Step-by-step explanation:

Given the following data;

Points on the x-axis (x1, x2) = (-4, 0)

Points on the y-axis (y1, y2) = (0, 6)

To find the equation of line;

First of all, we would determine the slope of the line.

Mathematically, slope is given by the formula;

Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis}

Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}}

Substituting into the equation, we have;

Slope, m = \frac {6 - 0}{0 - (-4)}

Slope, m = \frac {6}{4}

Slope, m = 1.5

To find the equation of line, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - 0 = 1.5(x - (-4))

y = 1.5x + 6
