Write the equation of the line that passes through the points (1,9) and (-1,1). Put

SpyIntel [72]

Answer:

Point slope form

y - 9 = 4(x-1)

Equation of the straight line passing through the point (1,9) and slope 'm' = 4 is 4 x - y +5=0

Step-by-step explanation:

Step(i):-

Given that the points are (1,9) and (-1,1)

slope of the line

$m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }$

m = $\frac{1-9}{-1-1}$

m = 4

step(ii):-

Equation of the straight line passing through the point (1,9) and slope 'm' = 4

y-y₁ = m( x-x₁)

y - 9 = 4(x-1)

y -9 = 4x-4

4 x - y -4+9 =0

4 x - y +5=0

Equation of the straight line passing through the point (1,9) and slope 'm' = 4 is 4 x - y +5=0

How do you work out this math problem?? 3x+15-9=2(x+2)

vovangra [49]

3x + 15 - 9 = 2(x +2)
3x + 6 = 2(x +2)
3x + 6 = 2x + 4
3x + 6 - 2x = 2x - 2x + 4
x + 6 = 4
x + 6 -6 = 4 - 6
x = -2
