## Teaching Graph A Line Using Slope And A Point On The Line Easily

Steps involved in plotting a line with the help of coordinate points, slope, and equation of a line.

Step 1: From the equation of line (y = mx + c), identify the slope m. If the equation is not in exact form, convert it first. “m” is the slope in the equation, and c is the constant.

Step 2: Recognise the (x,y) coordinate in the given problem and solve the above equation to find the value of c.

Step 3: Locate y-intercept (0, c) and coordinate point (x,y) on graph .

Step 4: Connect these coordinates and extend this straight line.

Q. Plot a line passing through (2,3) and having a slope of 5.

Solution: slope = 5;

Line equation: y = 5x + c

Putting (2,3) in x and y

3 = 5(2) + c

3 = 10 + c

c = -7

Putting c = -7 in y = 5x + c.

y = 5x - 7

So, y-intercept = (0, -7).

Now, plot (0, -7) and ...
