A line with a slope of –2 passes through the point (–4, 8). What is the equation of the slope-intercept form?
zloy xaker [14]

Answer:

y= -2x

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Given that the slope is -2, m= -2.

subst. m= -2 into the equation:

y= -2x +c

To find the value of c, substitute a coordinate.

When x= -4, y=8,

8= -2(-4) +c

8= 8 +c (expand)

c= 8-8 (-8 on both sides)

c=0 (simplify)

Thus, the equation of the line is y= -2x.

Maci made $170 grooming dogs one day with her mobile dog grooming business. She charges $60 per appointment and earned $50 in ti
V125BC [204]

Answer:

170  = 60x + 50 (let x be number of appointments)

Step-by-step explanation:

because the total is 170, it goes behind the equal sign. $50 in tip is added to the amount of appointments so it goes on the other side of the 170. the $60 per appointment goes on the 50's side

If f(x)=x/2-3 and g(x)=3x²+x-6 find (f+g)(x)
Ber [7]

Answer:

(f+g)(x) = 3x² + (3/2)X - 9

Step-by-step explanation:

f(x) = 1/2*x - 3

g(x) = 3x²+x-6

then (f+g)(x) i f(x) + g(x)

1/2*x - 3 + 3x²+x-6

3x² + 1.5X - 9

3x² + (3/2)X - 9
