Question

The equation for the line passing through (1.9,0) and (0,-1.6) is:

A. y = 0.8421x - 1.6
B. y = 0.8421x + 1.6
C. y = -0.8421x - 1.6
D. y = -0.8421x + 1.6

Answer 1

The equation for the line passing through the points (1.9,0) and (0,-1.6) is y = 0.8421x - 1.6.

Step-by-step explanation:

To find the equation for the line passing through the points (1.9,0) and (0,-1.6), we need to calculate the slope and the y-intercept.

Slope:

The formula for calculating the slope is (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. Using the coordinates (1.9,0) and (0,-1.6), we have:

Slope = (0 - (-1.6)) / (1.9 - 0) = 1.6 / 1.9 = 0.8421

Y-Intercept:

The y-intercept is the value of y when x is 0. Using the point (0,-1.6), the y-intercept is -1.6.

Therefore, the equation for the line passing through the points (1.9,0) and (0,-1.6) is y = 0.8421x - 1.6.
