 Linear-equations/696683: Hi. My teacher makes us use www.assistments.org and the problems on there are really hard because I dont understand them. If you get a certain amount wrong, you get locked out and you have to try again another day. I dont understand the linear equations because my teacher does the notes too fast for me to keep up with the lesson. How can I? Write a linear equation in the form "y = ______________" using the following information about the equation: X-intercept of the equation: -10 Y-intercept of the equation: 3 1 solutions Answer 429237 by stanbon(57307)   on 2012-12-23 20:32:35 (Show Source): You can put this solution on YOUR website!Write a linear equation in the form "y = ______________" using the following information about the equation: X-intercept of the equation: (-10,0) Y-intercept of the equation: (0,3) ================ slope = (3-0)/(0--10) = 3/10 ----- Equation: y = mx + b y = (3/10)x + 3 =================== Cheers, Stan H. ===================

If you get a certain amount wrong, you get locked out and you have to try again another day. I don't understand the Evaluating Functions. I dont even remember us learning about it. Use the equation 7m - 11m = n to find m when n = 4. 1 solutions Answer 429236 by stanbon(57307)   on 2012-12-23 20:26:09 (Show Source): You can put this solution on YOUR website!Use the equation 7m - 11m = n to find m when n = 4 ---- Substitute for "n" and solve for "m": ---- 7m - 11m = n -4m = n ----- -4m = 4 ---- Divide both isdes by -4 to get: --------- m = -1 =========== Cheers, Stan H.
