Question

hi:}
two lines defined by the equation y=2x+4 & y=3x+b
where m and b are constant, intersect at the point (6,10) what is the value of b +m??

Answer 1

to find the point of intersection, solve the equations of lines simultaneously !
y= 2x+4
y= 3x+b

so,
2x+4 = 3x+b
and since intersection point has x= 6
just plug in x = 6 in this and you'll get b
