What is y−6=−4(x+2) in slope-intercept form?

Slope-intercept form is y=ax+b.

y-6=-4(x+2)

Simplify

y-6=-4x-8

+6 both sides

y=-4x-2

The answer is y=-4x-2.

The slope-intercept form: y = mx + b

y - 6 = -4(x + 2)        use distributive property

y - 6 = (-4)(x) + (-4)(2)

y - 6 = -4x - 8       add 6 to both sides

m = -4 - slope

b = -2 - y-intercept

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

probably the last option
