I need help finding the slope, The y-intercept, and the equation??

y intercept is (0, 1)

slope is 3

equation is y = 3x +1

Step-by-step explanation:

You find the y intercept when x equals 0 and you can see that on the table that is 1.

You find slope by y2-y1 divided by x2-x1. if you pick (0,1) and (1,4) it is 4-1/1-0 which equals 3.

Therefore the equation is y = 3x + 1 in slope intercept form because the slope is 3 and y int is 1.

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
