Answer:
y=-3x+10
Step-by-step explanation:
Slope formula y2-y1/x2-x1
7-1/1-3
simplify
6/-2
simplify
-3
now plug -3 into y=mx+b
y=-3(x)+b
choose any point and plug it into the equation, I am using (3,1)
1=-3(3)+b
simplify
1=-9+b
add 9 to both sides
b=10
plug into slope-intercept form
y=-3x+10
Answer:
Parallel lines have no solutions.
Explanation:
The slope of a parallel line is 0, so there’s no solution.
Answer:
2000×0.004=8
Step-by-step explanation:
Isolate the variable by dividing each side edit its factors that don't contain the variable
Bill moves at 45 feet per minute and Greg 75 per minute and starts with a constant of 20 feet from them.
Let X be the number of minutes
Bill*Minutes +Greg*Minutes +20 = total distnce between
45x + 75x +20 = d
Plug in 2.5 for both values of x
45(2.5) + 75(2.5) + 20 =d
Multiply values by 2.5
112.5 + 165 + 20 = d
add together
Distance = 297.5 feet apart
