For the graph's y-intercept, you can easily tell where the y-intercept is by looking at where it crosses the y-axis.

For the graph's slope, you can do rise over run (using two points).

For the table, the y-intercept is when x is 0. If there is not a point that has an x-coordinate of 0, you can find the change between the other points and work backwards.

For the table, the slope can be found using the slope formula and two points.

Slope Formula

(y2-y1)/(x2-x1)

Once you have found these values, you can easily compare the two.

Solve the system of equations by substitution - 5x+8y= -86 <br>y=6x-43 ​
n200080 [17]

Answer:

(6 ,-7)

Step-by-step explanation:

- 5x + 8y =  - 86 \\ y = 6x - 43 \\  - 5x =  - 86 - 8y \\ x = 17.2  + 1.6y \\ y = 6(17.2 + 1.6y) - 43 \\ y = 103.2 + 9.6y - 43 \\ 8.6y =  - 60.2 \\ y =  - 7 \\

x = 17.2 + 1.6( - 7) \\ x = 17.2  - 11.2 \\ x = 6

The numerical coefficient of -2pqr
VMariaS [17]

Answer:  -2

Explanation: The coefficient is the number to the left of the variable.

Another example would be that 10xy has the coefficient 10.

Something like x^2 has coefficient 1 because x^2 = 1x^2.

For the graph y = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an
svetlana [45]
<span>For the graph y = 1, the slope of a line that is perpendicular would be infinity because it lies vertically. The slope of the line parallel to it will have the same slope with y=1 which is zero because it lies flat or horizontally. Hope this answers the question. Have a nice day.</span>
