a line has the equation 2x + 5y = 7. another line passes through (3,6) and (k,9). what value for "k" will make the lines parallel? please tell me HOW to do this, too! thanks!

Step 1
First, we need to find the slope of the line 2x + 5y = 7. To do this, we can rearrange the equation into slope-intercept form (y = mx + b) by solving for y: 2x + 5y = 7 5y = -2x + 7 y = (-2/5)x + 7/5 So the slope of this line is -2/5. Show more…
