Answer:
y=
Step-by-step explanation:
Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept
y=mx+b
2=
(8)+b
2=4+b
B=-2
y=
Answer:
y=-2/3 x +4
Step-by-step explanation:
slop = (6-0)/(-3-6)= -2/3
c= 4 (when x =0)
line equation:
y= mx + c
y=-2/3 x +4
Rearrange the equation to standard form of a quadratic equation (ax^2+bx+c=0) by switching sides: 5x^2+2x-12=0. Now, use the quadratic equation formula to solve. You should come out with x_1=sqrt61-1/5 and x_2=-1+sqrt61/5. Thus, your answer is B, or two solutions.
