Answer:
y =5
Step-by-step explanation:
m=
−9−7
5−5
=
−16
0
=0
y=mx+b
5=(0)(7)+b
b=5
therefore y = 5
Answer:
the slope is 4
Step-by-step explanation:
y+3=4(x-5)
This is in point slope form
y-y1=m(x-x1)
where (x1,y1) is a point on the line and m is the slope
The slope is 4 and a point on the line is (5,-3)
Y = - 20x + 100
Slope is -20, y-intercept is 100.
Answer:11km/hr
Step by step explanation
In 1hr a cyclist travels 10 km so multiply 10 by 2 then he travels 13 km in 1 hour so keep it the same add 10(2)+13 to get 33 it took him 3 hrs in total to travel this distance so you must then divide 33 by 3 and you get average speed 11 km/hr
Collect like terms:
(7x+4x)−2y
Simplify:
11x-2y
