Question

Sketch and write the equation for each line : y = mx
+b

Answer 1

equation y =7/4x+1

slope = 7/4

Explanation:

We have two points so we can find the slope

m =(y2-y1)/ (x2-x1)

= (4--3)/(2--2)

= (4+3) / (2+2)

= 7/4

We know the slope and the y intercept

We can write the equation using y = mx+b where m is the slope and b is the y intercept

y= 7/4x +1

We put at dot at (0,1) and then go up 7 and to the right 4 . We put another dot

Connect the dots and we have our line.

We could also put dots at (-2,-3) and (2,4) and connect the dots.
