I need a picture or an example to help you. To identify the slope and y-intercept you have to do slope intercept form. Y=mx+ b or y=slope+ y intercept. If you are looking at a graph then, the y intercept is the only point on the y axis. To find the slope on a graph you have to count how much the point rises and moves from each point. Like, if my point was (1,3) and the next point was (3,4). To get to (3,4) you would have to go up 1 and move 3 spaces to the right. Your slope would be 1/3.

Answer:
1/2
Step-by-step explanation:
A childs ticket = $28 and an adult = $45
Total Cost to each family is the number of adult tickets bought multiplied by "x" PLUS the number of child tickets bought multiplied by "y"
Henson's equation = 3x + y = 163 Garcia's equation = 2x + 3y = 174
using the substitution method we need to express either x or y in terms of the other variable. In this example looking at the Henson equation it is very easy to express y in terms of x.
Rewrite the Henson equation to make y the subject y = 163 - 3x Substitute this value (163 - 3x) for "y" in the Garcia equation which now becomes
2x + 3(163 - 3x) = 174 Expand the bracket 2x + 489 - 9x = 174 -7x + 489 = 174 Add 7x and subtract 174 from both sides of the equation 315 = 7x 315/7 = x 45 = x An adult ticket costs $45 Substitute this back into the Henson equation 3 * 45 + y = 163 135 + y = 163 y = 163 - 135 = 28 A childs ticket costs $28
Check in the Garcia equation 2 * 45 + 3 * 28 = 90 + 84 = 174 = CORRECT
A childs ticket = $28 and an adult = $45
