Q. What is the equation of the line that passes through the point (2,5) and has a slope of 3 ?Answer:
Identify Equation Form: Identify the slope-intercept form of a line's equation.The slope-intercept form of a line's equation is y=mx+b, where m is the slope and b is the y-intercept.
Find Y-Intercept: Use the given slope and point to find the y-intercept b. We know the slope m is 3 and the line passes through the point (2,5). We can substitute these values into the slope-intercept form to find b. 5=3(2)+b
Solve for b: Solve for b.5=6+bSubtract 6 from both sides to isolate b.5−6=b−1=b
Write Line Equation: Write the equation of the line using the slope and y-intercept.Now that we have the slope m=3 and the y-intercept b=−1, we can write the equation of the line.y=3x−1
