Answer 1

Answer:

y =3x + 6

Step-by-step explanation:

The gradient of a line is its slope, the rate of change of y with x.

The gradient (m) of the line in question is said to be:

• 3 unitz

m = 3

The same line passes thru the point, (x₁, y₁):

• (-1, 3)

x₁ = -1

x₁ = -1y₁= 3

Line of 'slope-point" form:

$\boxed{ \mathsf{y - y _1 = m(x - x _1 ) }}$

putting the values in place

y - 3 = 3(x - (-1))

two minus make a plus

y - 3 = 3(x + 1)

y - 3 = 3x + 3

isolating y (sign of 3 changes as it changes its side)

y = 3x + 3 + 3

y = 3x + 6

That is the required equation of the line.
