Write an equation for the line through the point (7,6) with slope -4 in point-slope form y = y_0 + m(x-x_0).

Pointp-slope form:
we neeed a point (x₀,y₀) and the slope "m".
y-y₀=m(x-x₀)

We have the point (7,6) and the slope:  m=-4.  therefore:
y-6=-4(x-7)

y-6=-4(x-7)

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
