What equation has slope of 3 and passes through 0,-2
suter [353]

Answer:

y = 3x - 2

Step-by-step explanation:

<em>use y = mx + b</em>

y = -2

x = 0

m (slope) = 3

b (y-intercept) = -2, <em><u>since the point (0,-2) passes through the y a</u></em>xis.

<em>put is as slope-intercept form:</em>

y = 3x - 2

Find the equation of the straight line passing through the point (0,1) which is perpendicular to the line y= -2x + 2
mylen [45]

Answer:

y = 1/2x + 1

In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.

-2 ⇒ 1/2

Next, we need to substitute the information given into the point-slope formula.

The point-slope formula is:

y - y₁ = m(x - x₁)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.
