For question 1, find the x- and y-intercept of the line. (1 point) Responses x-intercept is 5; y-intercept is . x -intercept is 5 ; y -intercept is Image with alt text: negative 10 . x-intercept is 8; y-intercept is . x -intercept is 8; y -intercept is Image with alt text: negative 4 . x-intercept is ; y-intercept is 5. x -intercept is Image with alt text: negative 10 ; y -intercept is 5. x-intercept is ; y-intercept is 8.
The x-intercept is unknown and the y-intercept is 8.
For question 2, find the x- and y-intercept of the line. 5x + 4y = 80 (1 point) Responses x-intercept is 4; y-intercept is 5. x -intercept is 4 ; y -intercept is 5. x-intercept is 20; y-intercept is 16. x -intercept is 20; y -intercept is 16. x-intercept is 5; y-intercept is 4. x -intercept is 5; y -intercept is 4. x-intercept is 16; y-intercept is 20. x -intercept is 16; y -intercept is 20.
To find the x-intercept of the line, we set y = 0 and solve for x.
5x + 4(0) = 80
5x = 80
x = 80/5
x = 16
To find the y-intercept, we set x = 0 and solve for y.
5(0) + 4y = 80
4y = 80
y = 80/4
y = 20
Therefore, the x-intercept is 16 and the y-intercept is 20.
Write in standard form using integers. (1 point) Responses Image with alt text: negative lower x minus 6 lower y equals 24 Image with alt text: negative lower x plus 6 lower y equals 24 Image with alt text: negative lower x plus 6 lower y equals 4
The correct response is:
Image with alt text: -x + 6y = 24
The grocery store sells kumquats for $4.75 a pound and Asian pears for $2.25 a pound. Write an equation in standard form for the weights of kumquats k and Asian pears p that a customer could buy with $22. (1 point) Responses 4.75k + 2.25p = 22 4.75 k + 2.25 p = 22 4.75k = 2.25p + 22 4.75 k = 2.25 p + 22 4.75 + 2.25 = k 4.75 + 2.25 = k 4.75p + 2.25k = 22
The equation in standard form for the weights of kumquats k and Asian pears p that a customer could buy with $22 is:
4.75k + 2.25p = 22
