Find the slope and y-intercept for y= -5 + 2x

Sagot :

Answer:

the slope: 2

y intercept: (0,-5)
ANSWER:

Slope: 2
Y-intercept: -5

BECAUSE:

We use the formula:
y=mx+b
m=slope
b=y-intercept

Since we have -5 where “b” would be, b=-5 and b is the y-intercept. So, the Y-intercept is -5
Since we have 2 where “m” would be, m=2 and m is the slope. So, the slope is 2


Tip:
When I am asked what is the y-intercept or slope and I am given an equation, I use this strategy:

The slope is whatever goes right before the “x” in the equation.
Example:
y= 1/5x + 4 (The slope is 1/5)
y= 3.5x + 8 (The slope is 3.5)
y= 4x + 2 (The slope is 4)

The y-intercept is whatever is left of the equation
Example:
y= 1/8x + 10 (The y-intercept is 10)
y= 4x + 9.5 (The y-intercept is 9.5)
y= 2.2x + 1/8 (They y-intercept is 1/8)
