Question

express x in terms of Y for the equation 4 x-y+ 7 = 0 find the point where the line meets x-axis

Answer 1

4x=y-7 => x =y/4 - 7/4 this is the expression for x in terms of y. to obtain the point where the line cuts x axis substitute y as zero in the line equations and solve for x.
the point where line meets x axis is (-7/4,0).
