Question 151365: graph linear equation y = 2x - 1. Answer by jim_thompson5910 (35256) ( Show Source ): You can put this solution on YOUR website! Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is. Since this tells us that the y-intercept is .Remember the y-intercept is the point where ...
Answer by tutorcecilia (2152) ( Show Source ): You can put this solution on YOUR website! y=1/2x [The slope is (1/2) the y-intercept is zero (but isn't shown) y= (1/2)x + 0. Plot the y-intercept (0,0). Using the slope of 1/2, move up one space from (0,0) and move to the left two spaces. Plot point (2, 1). From (2,1) move up one space and over ...
Using these values, we draw the graph of the given straight line. The graph looks as follows: So from the above graph, when x takes the value 7, the value of y is 15. So in a similar way when x = 3 1/2, that is 7/2 then the value of y is 8. This point is obtained by plugging in the value of x in the given equation. Y = 2(7/2) + 1 y = 7 + 1
SOLUTION: Graph the line y=-1/2x+2. You can put this solution on YOUR website! Equation describes a sloping line. For any. equation ax+by+c = 0, slope is . X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 2/0.5 = 4. Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b.
So this is the graph of through the points (-5,9) and (-4,7) So from the graph we can see that the slope is (which tells us that in order to go from point to point we have to start at one point and go down -2 units and to the right 1 units to get to the next point), the y-intercept is (0, )and the x-intercept is ( ,0) ,or ( ,0)
Answer by algebrahouse.com (1659) ( Show Source ): You can put this solution on YOUR website! Slope-intercept form is y = mx + b. m is the slope. b is the y-intercept. Slope = rise/run = vertical change/horizontal change. For y = -2x - 1. - put a point at -1 on the y-axis. - from there, since the slope is -2/1, move down 2 and to the right 1 ...
Step 1: Finding the Vertex. Step 2: Finding two points to left of axis of symmetry. Step 3: Reflecting two points to get points right of axis of symmetry. Step 4: Plotting the Points (with table) Step 5: Graphing the Parabola. In order to graph , we can follow the steps: Step 1) Find the vertex (the vertex is the either the highest or lowest ...
An easy way to make a graph is to plot two points. When x=0, y=-1; and when x=1, y=1. Plot these two points and make a straight line going through them (since it's a linear equation) and you have your graph! Here is a picture:
SOLUTION: Graph y=1/2x-3. You can put this solution on YOUR website! So here's another point (-6,-6). Add this to our graph. We could graph this equation another way. Since this tells us that the y-intercept (the point where the graph intersects with the y-axis) is (0, ). Now since the slope is , this means that in order to go from point to ...
Determine the acute angle at which y = 2x - 1 and y = 0.5x + 2 intersect. The two lines and the x-axis form a triangle. Find the appropriate angles at the axis.
