Q. 6 Graph a bine that has a slope of −43 and inclubes the point (−3,2)
Use Slope-Intercept Form: First, we need to use the slope-intercept form of a line, which is y=mx+b, where m is the slope and b is the y-intercept.
Calculate Equation with Slope: Since we know the slope m is −43, we can start with y=−43x+b.
Find Y-Intercept: Now we need to find the y-intercept b using the point (−3,2) that the line passes through. We plug these values into the equation: 2=−(43)(−3)+b.
Solve for Y-Intercept: Solving for b, we get 2=49+b. To find b, we subtract 49 from both sides: 2−49=b.
Final Equation of Line: Converting 2 to 48 to subtract, we get 48−49=b, which simplifies to b=−41.
Graph Y-Intercept: Now we have the full equation of the line: y=−(43)x−41.
Use Slope to Find Point: To graph the line, we start at the y-intercept (0, -rac{1}{4}) and use the slope to find another point. From (0, -rac{1}{4}), we go down 3 units and right 4 units to plot a second point.
Draw Line Through Points: Draw a straight line through the two points to complete the graph of the line.
