Write an equation in slope intercept form of the line that passes through the point (-5, -1) with slope -3.

Neporo4naja [7]

Answer:

y= -3x-16

Step-by-step explanation:

slope intercept form is written as y=mx+b. m is the slope, and b is the y-intercept. -3=m

we know that (-5,-1) is 5 points away from the origin, and that the slope is -3, so 5 times -3 equals -15. subtract 15 from -1 (y-coordinate) in order to get the y-intercept (when x=0).

0, 3, 8, 15, 24
y = x² + 2x

Step-by-step explanation:

<u>The pattern is</u>

Step 1 ⇒ 1*3 = 3
Step 2 ⇒ 2*4 = 8
Step 3 ⇒ 3*5 = 15

<u>Next step would be</u>

Step 4 ⇒ 4*6 = 24

<u>Step zero would be</u>

Step 0 ⇒ 0*2 = 0

<u>The equation</u>

y = x(x + 2) = x² + 2x
