Here's a graph of a linear function. Write the equation that describes that function. (Express it in slope-intercept form.)
rusak2 [61]

Answer:

y=\frac{1}{2}x+4

Step-by-step explanation:

The equation of a linear function in a slope-intercept form is written as

y=mx+q

where

m is the slope of the line

q is the y-intercept

We proceed as follows. First of all, we find the y-intercept, which is the value of y at which the line touches the y-axis.

From the graph, we see that this occurs at y = 4, therefore the y-intercept is

q=4

Now we have to find the slope. We do that by choosing two points along the line, with coordinates (x_1,y_1) and (x_2,y_2) and by using the equation

m=\frac{y_2-y_1}{x_2-x_1}

Here we take the two points:

(0,4)

(-8,0)

So the slope is

m=\frac{4-0}{0-(-8)}=\frac{1}{2}

Therefore, the equation of the line is

y=\frac{1}{2}x+4

The junior varsity football team score 23 points in last Saturday's game they score the combination of seven point touchdowns in
frutty [35]

Answer:

  2 touchdowns, 3 field goals

Step-by-step explanation:

The number of touchdowns cannot be more than 3, so it is relatively easy to find the solution by trial and error.

  23 is not divisible by 3, so 0 touchdowns is not a solution

  23 -7 = 16 is not divisible by 3, so 1 touchdown is not a solution

  23 -14 = 9 is divisible by 3, so 2 touchdowns and 3 field goals is a solution

  21 -21 = 2 is not divisible by 3, so there is only one solution.
