write slope form of lines satisfying the given coditions then use the point slope form of the eqation to write the slope intercept form of the equation slope = 4, passsing through (-3,9)

Here is how to find the equation of the line using point-slope form

Formula for the equation of a line in point-slope form: y - y₁ = m(x - x₁)

Now that we have the formula, we plug in what we are given.

y - 9 = 4(x + 3)

We can covert this into slope-intercept form by solving for y.

Our equation for this line is: y = 4x + 21.

We can prove this by graphing the line, like so:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
