1. Problem Description

The problem is to graph the linear equation 4x+7y=74x + 7y = -7.

2. Solution Steps

To graph the equation 4x+7y=74x + 7y = -7, we can find two points on the line and then draw the line through those points. We can find the intercepts.
To find the xx-intercept, set y=0y = 0 and solve for xx:
4x+7(0)=74x + 7(0) = -7
4x=74x = -7
x=74x = -\frac{7}{4}
So, the xx-intercept is (74,0)(-\frac{7}{4}, 0) or (1.75,0)(-1.75, 0).
To find the yy-intercept, set x=0x = 0 and solve for yy:
4(0)+7y=74(0) + 7y = -7
7y=77y = -7
y=1y = -1
So, the yy-intercept is (0,1)(0, -1).
We can plot the points (1.75,0)(-1.75, 0) and (0,1)(0, -1) on the graph and draw a line through them.
Alternatively, we can rearrange the equation to slope-intercept form: y=mx+by = mx + b, where mm is the slope and bb is the yy-intercept.
4x+7y=74x + 7y = -7
7y=4x77y = -4x - 7
y=47x1y = -\frac{4}{7}x - 1
The yy-intercept is 1-1, which means the line passes through (0,1)(0, -1). The slope is 47-\frac{4}{7}. This means that for every 7 units we move to the right, we move 4 units down. So, starting from (0,1)(0, -1), we can move 7 units to the right and 4 units down to reach the point (7,5)(7, -5).

3. Final Answer

y=47x1y = -\frac{4}{7}x - 1
