The slope of the line that contains the points (1, -1) and (2, 3) is 4. What is the y-intercept?

1 answer:

4 0

Y- intercept =-5
y-y1=m(x-x1)
y-(-1)=4(x-1)
y+1=4(x-1)
y+1=4x-4
y=4x-4-1
y=4x-5
Or
y=4x+b
-1=4(1)+b
-1=4+b
-1-4=b
-5=b. Y-intercept is -5

HACTEHA [7]

Answer:

m = $\frac{y-b}{x}$

Step-by-step explanation:

Given

y = mx + b ( isolate the term in m by subtracting b from both sides )

y - b = mx ( divide both sides by x )

$\frac{y-b}{x}$ = m

In a basketball game 15 of 20 foul shots that Michelle attempted were successful. What percent of her shots were not successful?

mestny [16]

Work 1:
Successful Percent:
15 divided by 20 equals .75
.75 times 100 is equal to 75
75%
Not successful Percent:
100% minus 75% equals 25%
25%
Work 2:
20 minus 15 equals 5
5 divided by 20 is equal to .25
.25 times 100 is equal to 25
25%
