13. The table represents some points of a linear function.
RUDIKE [14]

Answer:

y=-4x-18

Step-by-step explanation:

To find the slope of the function, you need two points in order, the first point having its x and y coordinates labeled as x1 and y1, and the second point having its coordinates labeled as x2 and y2. then, use the equation for slope, which is m=(y2-y1)/(x2-x1), and plug in the numbers. You should get m=(-10+2)/(-2+4)= -8/2= -4.

Then, use the slope and a point on the graph, and plug it into point slope form, which is y-y1=m(x-x1). No matter what point you use, you should get the same thing. I used the point (-2, -4). Using this point, the steps to arrange the equation in slope intercept form is: y+2=-4(x+4)=> y+2=-4x-16 => y=-4x-18.

The area of a triangle whose height is 1 more than 6 times it’s base is 13 square feet. If the base of the triangle is x feet wh
fredd [130]
Area of a triangle: A= 1/2(base)(hieght)

base=x
height= 6(base)+1= 6x+1

13= 1/2 × (x)(6x+1) 
(get rid of 1/2 by multiplying each side by 2)
26= (x)(6x+1)
26= (x × 6x)= 6x² (x × (+1))= x
26= 6x² + x
0= 6x²+x-26


Are either of those the answers? If not, list the options and I will be able to tell you which one is correct. Hope this helped!

Which of the following ordered pairs could represent the y-intercept of a function.
snow_lady [41]
<h3>Answer: (0,5)</h3>

This is because the x coordinate is 0. For any y intercept, the x coordinate is always 0 as this indicates the point is on the y axis.

Contrast this with something like (9,0) and we see that y = 0 indicating this point is an x intercept (it is on the x axis).
