Explanation:
y-7=4(x-2)
we need to simplify the y to het a
y-7=4x-8 (i did 4x-8 because of 4(x-2)
now y= 4x-8+(-7)
after calculating -8+(-7) IT becomes
y=4x-15
okay we have the guide Line
y=4x-15
the a is 4
because
a = {y=a.x+b}
now we need to find the points using this guide Line
y=4x-15
x= 2(you can add any number here ,we Just need to know where the point is )
y= 4(2)-15
y=8-15
y= -7
points are (2,7)
