Whats the point of intersection between these two lines?<br><br>x+y=10<br>x+2y=14
Yakvenalex [24]
You have to make an equation that i forgot what was called but you just take
x+y=10 and multiply it by -2 so the y’s can cancel out

so you’ll end up with:

-2x-2y= -20
(+) x+2y=14

you’ll get : x = -6


then you plug in -6 for x, solve for y and your coordinates will be

(-6 , 10)

What is the slope and the y-intercept of the graph of the linear function shown on the grid ?
VladimirAG [237]

Answer:

Slope: -1/4; Y-Intercept: 1.5

Step-by-step explanation:

Step 1: Find the slope. The best way to do this is to transform the two given points to y=mx+b form. When given two points, the best way to find the slope will be to do y2-y1/x2-x1. In this equation it would be -2-0/2+6, which is -2/8, simplified is -0.25 or -1/4. So we have the slope, which can determine the length of the line.

Step 2: Find the Y-Intercept. Finding the Y-intercept is so much simpler when given a graph, since all you have to do is find where the line goes through the y-axis, which in this case is (0,1.5), meaning that the y-intercept is 1.5 <em>(note: the y-intercept can also be found when x=0, for example (0,9).</em>

Hope this helped, good luck!

12. Todd graphs a quadratic function. The graph of his quadratic
seraphim [82]
Answer: A

You already know that the y-intercept in -32 for every equation by plugging in 0 for x, so disregard the coordinate (0,-32). Plug in -2 and 4 as your x values and check if they are equal to your y-value 0.
