Answer:

y= 11

Step-by-step explanation:

\boxed{slope =  \frac{y _{1} - y_2 }{x_1 - x_2} }

Substituting the coordinates and value of slope:

\frac{y - ( - 3)}{3 - ( - 4)}  = 2

\frac{y + 3}{3 + 4}  = 2

\frac{y + 3}{7}  = 2

Multiply both sides by 7:

y +3= 2(7)

y +3= 14

Subtract 3 from both sides:

y= 14 -3

y= 11

How do graphs and equations reveal information about a relationship between two quantities
ohaa [14]
When two quantities have a relationship, there is a corresponding equation that could describe it. These two quantities may be expressed in variables of x and y. When you plot the graph, you may see a line or a curve. This presents the trend of the relationship of the two quantities when the independent variable changes.

Solve for x<br> pls show work<br> 1/2x + 4 = 1/8x + 88
SVETLANKA909090 [29]

Answer:

224

Step-by-step explanation:

1/2x+4=1/8x+88

1/2x-1/8x+4=88

1/2x-1/8x=88-4

4/8x-1/8x=84

3/8x=84

x=84/(3/8)

x=(84/1)(8/3)

x=672/3

x=224
