Q. Find the slope and y-intercept of the line through the points:(2,−8) and (1,−2)slope =y-intercept =
Calculate Slope: To find the slope m of the line passing through two points (x1,y1) and (x2,y2), we use the slope formula:m=x2−x1y2−y1Let's plug in the values from the points (2,−8) and (1,−2).m=1−2−2−(−8)
Simplify Slope Calculation: Simplify the calculation for the slope.m=(−2+8)/(1−2)m=6/−1m=−6The slope of the line is −6.
Calculate Y-Intercept: To find the y-interceptb, we can use the slope-intercept form of a line, which is y=mx+b. We can use either of the two points for this calculation. Let's use the point (2,−8).−8=(−6)(2)+b
Solve for Y-Intercept: Solve for b, the y-intercept.−8=−12+bb=−8+12b=4The y-intercept of the line is 4.
