Question

Call line that passes through the point x, y with a y intercept of b and a slope of m can be represented by the equation y=mx + b. a line is drawn on the coordinate plane that passes through the .3, -6 and has a slope of four the y-intercept of the line is

Answer 1

Answer: (0, -7.2)

Explanation:

Substituting into point-slope form, the equation is

`y+6=4(x-0.3)`

The y-intercept is when x=0, so substituting in x=0,

`y+6=4(-0.3)\\\\y+6=-1.2\\\\y=-7.2`

So, the y-intercept is (0, -7.2).
