Diagram shows two perpendicular straight lines, ob and cbd, drawn on a cartesian plane. find(a)the equation of the straight line cbd(b)the-x intercept of the straight line dq

(a) y = -3x + 10

Step-by-step explanation:

The slope of line CD is perpendicular to line OB, which means they have opposite and reciprocal slopes.

Step 1: Find the slope of OB using the formula:

(x₁, y₁) = (0, 0) and (x₂, y₂) = (3, 1)

Step 2: Find the slope of CD (opposite and reciprocal of OB)

Step 3: Input the perpendicular slope and the slope into the Point-Slope formula: y - y₁ = m(x - x₁)

(x₁, y₁) = (3, 1) because it is the point the line will pass through

y - 1 = -3(x - 3)

y - 1 = -3x + 9      distributed -3 into (x - 3)

y      = -3x + 10    added 1 to both sides

***********************************************************************

The x-intercept of DQ is the same x-intercept as CD.  The x-intercept is when y = 0

y = -3x + 10

0 = -3x + 10

-10 = -3x       subtracted 10 from both sides

   divided both sides by -3

hi there!

the answer will be d: 2

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
