Question

Help me solving number 22 & 24. Thanks:)

Answer 1

Answer:

Question 22

x intercept is 7

y intercept is 4

The answer is C

Question 24

x intercept is -4

y intercept is 7

The answer is B

Step-by-step explanation:

x and y intercepts are the points at which the graph meets x and y axes.

x and y intercepts can be found the following way,

y intercept - substitute 0 to x

x intercept - substitute 0 to y

Question 22

$7y=28-4x$

Substitute x=0 to find the y intercept

$7y=28-4*0$

=$7y=28$

=$y=4$

Substitute y=0 to find x intercept

$7*0=28-4x$

=$0=28-4x$

=$4x=28$

=$x=7$

Therefore,

x intercept is 7

y intercept is 4

The answer is C

Question 24

$4y=7x+28$

Substitute x=0 to find the y intercept

$4y=7*0+28$

=$4y=28$

=$y=7$

Substitute y=0 to find x intercept

$4*0=7x+28$

=$0=7x+28$

=$-7x=28$

=$x=-4$

Therefore,

x intercept is -4

y intercept is 7

The answer is B
