You can put this solution on YOUR website! find the slope x intercept and y intercept of each line
1.)3x-y=6
2.)2x=4y=7 (Why are 2 equal signs here?
find the slope intercept form of the equation of the line passing through the point (3,-5) with a slope of -4
1.
3x - y = 6
- y = -3x + 6
Therefore, slope =
For x-intercept, set y to equal 0
0 = 3x - 6
x = 2....x-intercept: ( , )
For y-intercept, set x to equal 0
y = 3(0) - 6
y = -6....y-intercept: ( , )
2.
2x=4y=7 (I cannot give an answer to an EXPRESSION with 2 equal signs)
3.
find the slope intercept form of the equation of the line passing through the point (3,-5) with a slope of -4
With the given information, the POINT-SLOPE form should be used
Point being: (3, -5) and slope, m, being - 4, we will have:
Substituting, we get: y - -5 = -4(x - 3)
y + 5 = -4x + 12
Therefore, the slope intercept form of the equation of the line is:
