Final answer:
To calculate the slope and y-intercept of the line passing through (6, -29) and (-4, 31), we use the slope formula (rise over run) and plug one of the points into the equation y = mx + b. The slope calculation yields -6 and using the point (6, -29) gives us a y-intercept of 7. However, these results do not match the provided answer choices, suggesting a possible typo.
Thus the corret opction is:c
Step-by-step explanation:
To find the slope (m) and y-intercept (b) of the linear equation in the form y = mx + b that contains the points (6, -29) and (-4, 31), we can use the two given points to calculate the slope and then use one of the points to solve for the y-intercept.
The slope m is calculated by the formula m = (y2 - y1) / (x2 - x1).
For our points (6, -29) and (-4, 31), this becomes m = (31 - (-29)) / (-4 - 6), which simplifies to m = 60 / (-10) = -6. This indicates that our initial options may contain a mistake as none of the provided options has a slope of -6.
Assuming that there is a typo in the given options, we can still proceed to find the y-intercept.
Using y = mx + b and one of the points, let's say (6, -29), we substitute m and the coordinates of the point into the equation: -29 = -6*6 + b. This simplifies to -29 = -36 + b, giving us b = 7.
However, this also does not match any of the provided options.
If we assume a typographical error either in the slope calculation within the options or in our calculation, we can still analyze the correct process for determining slope and y-intercept.
Yet, the final answer should be recalculated or clarified to avoid any confusion.
