When x=0 y=50 when y=0 x=+\-5. -x^2 makes the parabola open downward y(x)=2x^2+50;y(3)=2*9+50=32
Answer is - 10
Step-by-step explanation:
Let the missing number be ‘x’
-8-x = 2
-x = 2 + 8
-x =10
x = -10
Y = 2x + 3
First, find the y-intercept (b). This is where the line meets the y-axis. The line meets the y-axis at 3, so the y-intercept is 3.
Now, find the slope (m) of the line. Slope is rise divided by run. The line goes up by 2, over by 1, up by 2, over by 1, and so on. So, the rise is 2 and the run is 1. 2 divided by 1 is 2, so the slope is 2.
Put these together into the equation to get y = 2x + 3.
Answer: she is thinking the line might go through the dots on the graph
Step-by-step explanation:
Because when you put the line through the dots on the graph it looks more efishiant. Sorry bad spelling.
