Is it 1 solution, no solution or infinite solution? -28 = -7(3x + 4) + 21

Identify an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined

Me! i will mark brainliest! i don't get polynomials and all that other stuff. so this question is really hard. multiply and simplify.(x - 4) (x^2 – 5x – 6)show your
