The equation of a line is
y=mx+b where m is the slope
In your example the slope is given as '4'
y = 4x +b Now put in the point you were given x,y 2, -3
-3 = 4(2)+b and solve to find b = -11 for your question
the line equation becomes
how you know that the slope is 4 ?
The line goes up '4' for every one x means slope is 4 slope is rise /run it rises 4 for 'run' of one = 4
thank you so much
that member give you the answer that i want to say you
