please solve for the point slope and slope intercept for all of the questions and show work. also please specify which answers go to which problem thank you so much

Step-by-step explanation:

y - = m( x - ) point - slope form of linear equation ;

y = mx + b slope-intercept form of linear equation, (0, b) are coordinates of y-intercept ;

(b). y - 3 = - 7(x - 8)

y = - 7x + 59

(c). y - (- 2) = [ x - ( - 7)] ⇔ y + 2 = ( x + 7)

y = x +

(d). y = - x + 9

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
