Question
A straight line has equation 8y = 4x + 21. Which of the following is true
Options
The slope is 0.5 and the y intercept is 2.6
The slope is 5 and the y intercept is 1.6
The slope is 0.5 and the y intercept is 1.6
The slope is 5 and the y intercept is 2.6
Solution
The slope is 0.5 and the y intercept is 2.6
Explanation;
Hint:
8y = 4x + 21
y = `4/8x + 21/8`
= `1/2 x + 21/8`
`1/2` = 0.5
`21/8` = 2.625
Slope = `1/2` = 0.5
y intercept = `21/8` = 2.6
