Answer:
g(5)=-19
Step-by-step explanation:
Plug in 5 for the x's and get g(x)=-3(5)-4 and then -15-4 which is -19 so g(x)=-19
The first graph is the solution for given table and the linear equation is y=3x+2.
<u>Step-by-step explanation:</u>
The linear equation of the line is y=mx+c.
where m is the slope and c is the y intercept.
The slope 

Choose two points (0,2) and(1,5).

y=3x+c.
To find the y-intercept value substitute (0,2) in the equation.
2=0+c.
c=2.
∴y=3x+2.
A) divide actual inches by scale:
28/7 =4 cm
B) multiply actual cm by scale:
9 x 7 = 63 inches
Rise=16, run=7. Slope is rise/run, and therefore is 16/7. The run is considered to be the x coordinate. Since the x coordinate on the point is 21, we know it has moved 3 exact points away from the origin (21/7=3). We can use this movement of 3 exact points to determine the y coordinate as well. Since the rise (y) is 16 for every exact point on a graph, we know the graph has risen 48 units (16x3=48). So, the point ends up being (21,48). The rate of change is 16cm per 7 minutes, or 2.28cm/minute. The equation is Y=(16/7)X (no y intercept because the graph starts at the origin). The equation gives you the y value of 48 when x is equal to 21.
