Solution
I see that you have uploaded an image of a worksheet for graphing linear equations. The instructions mention plotting lines with various given conditions. Let's break down the tasks step by step:
Tasks:
-
Line through (-5, -2) and intersecting the x-axis at -4:
- You have two points: (-5, -2) and (-4, 0) (x-intercept).
- Use the slope formula to find the slope.
- Then use the point-slope form to find the equation of the line.
-
Line with y-intercept 3 and x-intercept -8:
- The slope can be found by using the points (0, 3) and (-8, 0).
- Again, use the slope formula and then find the equation using point-slope form or slope-intercept form .
-
Given equation :
- Simply graph this by identifying the slope and y-intercept.
-
Line with y-intercept -3, parallel to line 2:
- A line parallel to line 2 will have the same slope as line 2.
- Use this slope and the given y-intercept to write the equation in slope-intercept form.
-
Line with y-intercept 8 and slope 1:
- The equation is .
-
Line with y-intercept -8 and slope -2:
- The equation is .
-
Line with x-intercept 8 and y-intercept 8:
- Use the points (8, 0) and (0, 8) to find the slope.
- Write the equation using the slope and one of the points.
-
Line parallel to line 3 with y-intercept -3:
- The slope will be , same as line 3.
- The equation will be .
-
Line through points (-6, 2) and (-1, 7):
- Use the slope formula and then the point-slope form to find the equation.
-
Line through the x-intercept of line 9 with slope -1:
- First, find the x-intercept of line 9 by solving the equation when .
- Use this point and the slope -1 to find the equation.
- Line with y-intercept 8 and slope -2:
- The equation is .
- Line passing through (5, 2) and the y-intercept of line 6:
- First, find the y-intercept of line 6 (which is -8).
- Use these two points, (5, 2) and (0, -8), to find the slope and equation.
Would you like a detailed solution for any of the lines, or do you need assistance with graphing?
