Question

Which of the following best describes the technique used to graph the equation using the slope and y-intercept? y = 5x + 10


A. Mark a point at 5 on the y-axis, go up 10 and left one and mark this point
B. Mark a point at 5 on the y-axis, go up 10 and right one and mark this point.
C. Mark a point at 10 on the y-axis, go down 5 and right one and mark this point.
D. Mark a point at 10 on the y-axis, go up 5 and right one and mark this point

Answer 1

What does 5 represent and what does 10 represent in the equation? That will take you to the solution.

Answer 2

D?

Answer 3

Seems so. 10 is the y-intercept, so that is where you start. 5 represents the slope, so as a fraction that is 5/1 (5 up / 1 right). Make sure you are clear on the ideas for the future.

Answer 4

Given the points (2, 3) and (6, 8), write the point-slope form of the equation.


A. y - 3 = x - 2
B. y - 3 = 5/4 (x - 2)
C. y - 8 = 4/5 (x - 6)
Could you help me?

Answer 5

Can you find the slope? Remember the form for pt-slope is (y-y1)=m(x-x1).
