The answers are 0 and 2
This can be found by looking at the x axis and finding every point where the line crosses
This line y = 4/5 x - 3 has slope = 4/5
Perpendicular lines, slope is opposite and reciprocal so slope of a line that is perpendicular to the line y = 4/5 x - 3 is -5/4
Answer
- 5/4
The solution to any system graphically can be found where the 2 graphs intersect. These two graphs intersect at the point (0, 2).
(x4−3x3+4x2−8)/(x+1) = x3−4x2<span>+8x−8.</span>
Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.
