A line has a slope of 3 and passes through the point (-3, 8). What is the equation of the line​
mixer [17]

Answer:

y=3x+17

Step-by-step explanation:

Slope formula y2-y1/x2-x1=m

y=3x+b

Find b (y-intercept), enter the given coordinates (-3, 8)

8=3(-3)+b

8=-9+b

b=17

y=3x+17

Hope this helps! Please mark brainliest :)

what is the equation, in slope- intercept form, of the line that contains the points (-3,4) and (5,7)
gavmur [86]

Answer:

y = \frac{3}{8} x + \frac{41}{8}

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

To calculate the slope use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)

m = \frac{7-4}{5+3} = \frac{3}{8}, hence

y = \frac{3}{8} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (5, 7 ), then

7 = \frac{15}{8} + c ⇒ c = 7 - \frac{15}{8} = \frac{41}{8}

y = \frac{3}{8} x + \frac{41}{8} ← equation in slope-intercept form
