How do i find an equation for a line with an x-intercept of 4 and a y-intercept of -2
ivann1987 [24]

Answer:

The equation of a line is y = ax + b, where a is the slope and b is the y-intercept.  

Since we have the y-intercept, all we need to do is find the slope. To find the slope, you need 2 coordinates.

The y-intercept is where the line crosses the y axis, so it is where x is 0. Since the y intercept is -2, that means the first coordinate is (0, -2)

The x-intercept is where the line crosses the x axis, so it is where y is 0. Since the x intercept is 4, that means the second coordinate is (4, 0)

Since we already have the y-intercept, all we do is put the slope in the equation: y = 1/2x - 2.

4 3/5 + 5 1/2<br> Help me please and thank you
Studentka2010 [4]

Answer:

Step-by-step explanation:

4 3/5 + 5 1/2= (10 1/10)

Step 1: Find the common multiple between the numbers, and simplify-

4 3/5=4 6/10 5 1/2= 5 5/10

Step 2: Convert to improper fractions-

4 6/10 as an improper fraction is 46/10 and 5 5/10 as an improper fraction is 55/10 (Formula for mixed numbers to improper fractions is denominator multiplied by whole number plus numerator)

Step 3: Add numerator of improper fractions, then add back denominator-

46+55=10 1 numerator:101 denominator:10 101/10

Step 4: Convert into mixed number-

101/10= 10 1/10

ANSWER: 10 1/10
