Question 1009627: Write the slope-intercept form of the equation with the given characteristics.
1. slope=1/4 ; y-intercept=2
2. slope=-3/2 ; passes through (-4,7)
3. passes through (-2,1) and (2,-5)
4. parallel to the line y=-3x+5 ; passes through (-4,5)
8. perpendicular to the line y=1/2x-8 ; passes through (7,-6)
Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
Basic understanding should be, the form is y=mx+b, and m is slope, and a point on the line, actually on the y-axis is (0,b). The formula can be solved for b, giving b=y-mx.
ONLY two of the questions you asked will be solved here.
#8
For perpendicular, you want negative reciprocal of for the slope, which is . Find the y-intercept using ;
the resulting equation then being .
With that one, you should know how to do #2 yourself.
#3
So far giving and you can find b;
pick either point of the line, maybe (-2,1);
The equation being looked for is .
