Answer:
y=4x-9
Step-by-step explanation:
Slope:
y2-y1=m(x2-x1)
subsitute the values
-5-3=m(1-3)
solve
-8=m-2
divide both sides by coefficient of x
/-2 /-2
4=m
y-intercept:
y=4x+b
subsitute
3=4(3)+b
solve
3=12+b
subtract 12 from both sides
-12-12
solve
-9=b

Answer:
X = 7.2
Step-by-step explanation:
Hello
For the triangle of right side, using Pytagoras:
(2.5)^2 + b^2 = 6^2
6.25 + b^2 = 36
b^2 = 36 - 6.25
b^2 = 29.75
b = 5.45
Now we can to find X using again Pytagoras:
3^2 + (5.45)^2 = x^2
9 + 29.75 = x^2
38.75 = x^2
X = 7.2
Best regards
