The slope is (4-3)/(7-2)=1/5
using the point (7,4), the point-slope form is y-4=(1/5)(x-7)
Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Mars a distance called 1 Astronomical Unit.
Answer:
y=3x-2
For plotting graph we have to put some x values in above equation then we get y Ans
when x=0,y=-2
when x=1,y=1
when x=2,y=4
when x=-1, y=-5
when x=-2, y=-8
Step-by-step explanation:
First you need to substitute the xs and ys into point slope ( y1 - y2 = m(x1 - x2). in this example it would be 3-6= m(0 - (-1)). then you just simplify, so -3 = m(1) -3=m. the slop is -3. because you already know the y-intercept is 3 (0,3), you can substitute everything into slope intercept (y=mx+b). so the answer is y=-3x+3.
I hope this helped, let me know if you are still confused and i can help :)
