Write the equation of the lines through the point (1, -1) (i) parallel to x + 3y - 4 = 0 (ii) perpendicular to 3x + 4y = 6. Solution : (i) Since the required line is parallel to the line x + 3y - 4 = 0 is, slopes of the required line and given line will be equal.
Solve Now
Find the equation of a line that goes through the point (1, 3) and has a slope of 2 . Step 1. Substitute slope for 'm' in y = mx + b. y = m x + b y = 2 x + b. Step 2. Substitute the point ( 1, 3) into equation. y = 2 x + b 3 = 2 ( 1) + b. Step 3.

Start with the point-slope formula ( x1 and y1 are the coordinates of a point on the line): y − y1 = m (x − x1) We can choose any point on the line for x1 and y1, so let's just use point (2,3): y − 3 = m (x − 2) We already calculated the slope m:
We can write an equation of the line that passes through points (3,5) and has a slope “6”. We know how to find the equation of a line Point Slope Form, so it can be simple how to find the
