Complete the equation of the graphed linear function in point-slope form.
vazorg [7]
The point-slope form:
y-y_1=m(x-x_1)
m - slope
x₁, y₁ - the coordinates of a point

It passes through the points (1,-2) and (2,2).
(1,-2) \\
x_1=1 \\ y_1=-2 \\ \\
(2,2) \\
x_2=2 \\ y_2=2 \\ \\
m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-2)}{2-1}=\frac{2+2}{1}=4

\boxed{y-(-2)=4(x-1)}

A line includes the points (9, -7) and (-6, -2). What is its equation in slope-intercept form?
Rus_ich [418]

Answer:

y=\frac{-1}{3}x-4

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

<em>m</em> - slope

<em>b </em>- y-intercept

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step 1: Define

Point (9, -7)

Point (-6, -2)

Step 2: Find slope <em>m</em>

<em />m=\frac{-2-(-7)}{-6-9}<em />

<em />m=\frac{-2+7}{-15}<em />

<em />m=\frac{5}{-15}<em />

<em />m=\frac{-1}{3}<em />

y=\frac{-1}{3}x+b

Step 3: Find y-intercept <em>b</em>

<em />-7=\frac{-1}{3}(9)+b<em />

<em />-7=-3+b<em />

<em />-4=b<em />

<em />

Step 4: Write linear equation in slope-intercept form

y=\frac{-1}{3}x-4
