Q. What is the equation of the line that passes through the point (2,5) and has a slope of 4 ?Answer:
Identify Slope-Intercept Form: Identify the slope-intercept form of a line's equation.The slope-intercept form 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 have the slope m as 4 and a point (2,5) through which the line passes. We can substitute these values into the slope-intercept form to find b. Using the point (2,5), we get: 5=4(2)+b5=8+b5−8=b−3=b
Write Line Equation: Write the equation of the line using the slope and y-intercept.Now that we have the slope m=4 and the y-intercept b=−3, we can write the equation of the line.The equation is y=4x−3.
