The slope-intercept form is y = mx + b.
First find the slope.
m = (y1-y2)/(x1-x2)
m = (-2-5)/(-4-1)
m = -7/-5
m = 7/5
looking for b.
y = mx+b
5 = (7/5)(1) + b
5 = (7+5b)/5
25 = 7+5b
18 = 5b
b = 18/5
so the slope-intercept equation is
y = (7/5)x + (18/5)
Answer:
15
Step-by-step explanation:
Gregory gained 86 dollars in total and he got this money by first getting 11$ and then 5$ for each question he solved correctly, so our equation is
11+5x=86 (x being the number of questions he answered correctly)
11+5x=86 (subtract 11 from both sides)
5x=75 (divide both sides by 5)
x=15
Gregory answered 15 questions correctly
Answer:
200/3 and 100/3
Step-by-step explanation:
Perimeter is equal to 2 times the value of the sum of the 2 sides
P = 2(L1 + L2)
since L1 + L2 = 3x, P would equal 6x.
divide 200 by 6 to get 100/3
plug this x value back into your side lengths
