Y=3x+2 is the equation of a straight line graph. Where does it cross the y-axis?

1 answer:

8 0

The line crosses the y-axis at point (0,2). You know this because the slope intercept form is y=mx+b. y is any point on the y-axis. m is the slope of the line. x is and point on the x-axis. Finally, b is the y-intercept or where the line crosses the y-axis. As a result, your equation has a 2 for b. So, your answer would be: the line crosses the y-axis at point (0,2). 2 being where the line crosses the y-axis.

A rectangle has a a perimeter of 72 ft. The length and width are scaled by a factor 3.5.

Ivanshal [37]

Perimeter of a rectangle:
P = 2 L + 2 W, P = 72 ft
P ( new ) = 2* 3.5 L + 2 * 3.5 W = 3.5 * ( 2 L + 2 W ) = 3.5 P
P ( new ) = 3.5 * 72 = 252 ft
Answer:
The perimeter of the new rectangle is 252 ft.
