Q. What is the equation of the line that passes through the point (−3,7) and has a slope of 31 ?Answer:
Identify slope-intercept 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 are given the slope m as 31 and a point on the line (−3,7). We can plug these values into the slope-intercept form to solve for b. 7=31(−3)+b
Solve for b: Perform the multiplication and solve for b.7=31×−3+b7=−1+b7+1=b8=b
Write line equation: Write the equation of the line using the slope and y-intercept.Now that we have the slope m as 31 and the y-intercept b as 8, we can write the equation of the line.y=31x+8
