Use the point-slope form of a line given by:
y−y1=m(x−x1)

Let (x1,y1)=(3,−4) and (x2,y2)=(7,0), the x-intercept so that the slope is:$m=\frac{y2-y1}{x2-x1}=\frac{0-(-4)}{7-3}=\frac{4}{4}=1$

So, the equation is:

y−(−4)=1(x−3)

y+4=x−3

y=x−7

Let (x1,y1)=(3,−4) and (x2,y2)=(7,0), the x-intercept so that the slope is:

So, the equation is:

y−(−4)=1(x−3)

y+4=x−3

y=x−7
